Diabetes Neuropathies: Prevention, Diagnoses and Treatments
Keeping your blood glucose levels as near to normal range is the best way of preventing neuropathy. This is the best way to protect the nerves throughout your body.
And how I know how difficult this can be. Especially at this time of year. Christmas is almost upon us and with it comes all the wonderful treats made for the season. Almost every home you go in to has platters of cookies, cakes, chip and dips, ciders and eggnogs. It is so very easy to over eat and ignore our blood sugars. Make sure you eat regular meals and take your insulin. I find that, if I have eaten and followed my regime, it is far easier to resist the temptations put in front of me. I will also take only a nibble or two of a treat. Maybe 2 or 3 chips. Or one cookie. And then leave the rest alone. At least I have had a taste and it doesn’t usually affect my blood glucose by very much at all.
Diagnoses of Diabetic Neuropathies:
Usually diabetic neuropathy is diagnosed by your doctor based on symptoms and physical exam. Your doctor will most likely check your heart rate, reflexes, muscle strength, and blood pressure. He/she may also test your sensitivity to changes in position, vibration, light touch, or temperature.
If you feel you have symptoms, talk to your doctor so that he can test you. We know our own bodies better than anyone and when it is not reacting normally to anything, we can tell. Listen to your body. If your feet are going numb, even slightly, let your doctor know. The same goes for your hands or any other part of your body. Don’t ignore warning signs like tingling, weakness, pounding in the ears, the sensation of hearing your own heartbeat, or even small injuries that you don’t feel at the time of injury. Early detection of neuropathies will help you and your doctor combat it.
Foot Exams:
Because I have signs of peripheral neuropathy now my doctor does a comprehensive foot exam about every six months, though it is recommended once a year for most diabetics. Your doctor will examine the skin, muscles, circulation, sensation and bones in your feet.
When I had my first exam at the diabetic clinic they used a feather, with me not looking, to see if I could feel it. I couldn’t. Then she used a nylon monofilament (like a bristle on a hairbrush), poking my feet with it, again with me not looking. (Some will use a pin instead). I could feel that.
These tests will indicate to your doctor whether you have lost the protective sensation in your feet (and other areas). Loss of sensation can cause you to develop foot sores or have unnoticed injuries that may not heal properly.
Your doctor may also use a tuning fork to test your sensitivity to vibration. It is more accurate than touch pressure. Checking temperature sensitivity is another test he may use.
Other Tests:
Though not often needed to diagnose neuropathy, there are other tests used to tell him what type of nerve damage there is and to what extent it has progressed.
To show how organs, like the bladder and urinary tract, preserve a normal structure and whether the bladder is emptying properly he may do an ultrasound.
Your doctor may check on the flow of electrical current through a nerve using a nerve conduction study. This can tell him what type of neuropathy is there and to what extent the nerves are damaged.
To test muscle response to electrical signals sent by nearby nerves he may order an electromyography.
A heart rate variability test will tell your doctor how the heart is responding to deep breathing and changes in blood pressure and posture.
Treatment of Diabetic Neuropathies:
The best and first treatment of diabetic neuropathies, and to prevent further damage, is to bring your diabetes under control and keep it in normal range. This will include taking medication and insulin as directed, planning meals, testing often for blood glucose levels, and physical activity.
As a note, the amount of physical activity you do can greatly affect your blood glucose levels and thereby affect how much insulin you will need to take.
To begin with your symptoms may seem to get worse, however getting and keeping your blood glucose levels controlled well will help lessen them in the long run.
For instance, at first I couldn’t see well. My vision was very blurry. As I got my blood glucose levels under control, the sugar build up at the back of my eyes that was causing the blurriness was lessened and, over time, my eyesight cleared. (As much as it ever does as I already wore glasses.) This was NOT caused by a neuropathy, but because I had gone undiagnosed for so long.
When you have high blood sugar that is uncontrolled it can cause a buildup of sugar/glucose behind the eyes, affecting vision. By bringing blood glucose under control, this will clear up and your vision will revert to what it normally was.
Keeping your blood glucose levels under control may also prevent or delay further problems. As scientists learn more, new treatments to help slow, prevent or even reverse the nerve damage may become available.
Other treatments depend on the type of nerve problem and symptom.
Pain Relief
Oral medications are usually used for painful diabetic neuropathy, though other treatments could help some. Those with severe nerve pain my find relief from a combination of medications and treatments.
Some oral medications used to help relieve diabetic nerve pain include:
tricyclic antidepressants, such as amitriptyline, imipramine, and desipramine (Norpramin, Pertofrane)
other types of antidepressants, such as duloxetine (Cymbalta), venlafaxine, bupropion (Wellbutrin), paroxetine (Paxil), and citalopram (Celexa)
anticonvulsants, such as pregabalin (Lyrica), gabapentin (Gabarone, Neurontin), carbamazepine, and lamotrigine (Lamictal)
opioids and opioid-like drugs, such as controlled-release oxycodone, an opioid; and tramadol (Ultram), an opioid that also acts as an antidepressant
Duloxetine and pregabalin are approved by the U.S. Food and Drug Administration specifically for treating painful diabetic peripheral neuropathy.
Many experts say to avoid over-the-counter medications like acetaminophen or ibuprofen. They may not work very well and can have serious side affects. Often antidepressants can help relieve pain. This does not mean you have to be depressed to have them be effective. Some medications are not recommended for use in older patients or those with heart disease. All medications have some side effects.
Topical treatments (applied to the skin) can be effective depending on your type of neuropathy. These include capsaicin cream and lidocaine patches (lidoderm, lidopain), as well as nitrate sprays or patches used on the feet for pain relief.
Studies of alpha-lipoic acid, an antioxidant, and evening primrose oil have shown that they can help relieve symptoms and may improve nerve function.
A device called a bed cradle can keep sheets and blankets from touching sensitive feet and legs.
Acupuncture, biofeedback, or physical therapy may help relieve pain in some people.
Treatments that involve electrical nerve stimulation, magnetic therapy, and laser or light therapy may be helpful and are being studied further. Researchers are also studying several new therapies in clinical trials.
Gastrointestinal Problems
Eating small, frequent meals, avoiding fats and eating less fiber can relieve mild symptoms of gastroparesis (indigestion, belching, nausea, vomiting). If your symptoms become severe erythromycin may be used to speed digestion or perhaps metoclopramide (which also helps to relieve nausea). There are other medications as well that help regulate digestion or reduce stomach acid.
I take a combination of Nexium and metoclopramide to help with the nausea, along with eating small meals frequently.
To relieve diarrhea or other bowel problems, doctors may prescribe an antibiotic such as tetracycline, or other medications as appropriate.
Dizziness and Weakness
Have you ever stood up too fast and had the room spin? A rapid change in blood pressure is the culprit in most cases. Blood pressure and circulation problems can cause light-headedness, dizziness, or fainting. Sitting or standing slowly may help. Raising the head of your bed, or wearing elastic stockings can also aid in preventing these episodes.
Treatment with salt-retaining hormones or increasing salt in the diet may be of benefit for some.
High blood pressure medications may be used.
When muscle weakness or loss of coordination is a problem, physical therapy may be of help
Urinary and Sexual Problems:
Drinking plenty of fluid can help prevent urinary tract infections. An antibiotic will most likely be prescribed if you do develop a urinary tract infection. For those who suffer from incontinence, urinating at regular intervals—every 3 hours, for example--- may be helpful as you may not be able to tell when the bladder is full.
To treat erectile dysfunction in men, the doctor will first do tests to rule out a hormonal cause. Some oral medications have been developed and are available to help men get and maintain an erection by increasing blood flow to the penis. There are also injections that are injected right into the penis or inserted into the urethra at the tip of the penis. Mechanical vacuum devices have also been used to increase blood flow to the penis. A surgically implanted inflatable or semirigid device in the penis have been used as well.
Vaginal lubricants may be useful for women when neuropathy causes vaginal dryness. To treat problems with arousal and orgasm, the doctor may refer women to a gynecologist.
Foot Care
The nerves affected most often by neuropathy are those to the feet. These nerves are the longest in the body. Loss of sensation in the feet means that sores or injuries may not be noticed and may become ulcerated or infected. Circulation problems also increase the risk of foot ulcers.
More than half of all lower-limb amputations occur in people with diabetes—86,000 amputations per year in the US alone. Doctors estimate that nearly half of the amputations caused by neuropathy and poor circulation could have been prevented by careful foot care.
Follow these steps to take care of your feet:
Clean your feet daily, using warm—not hot—water and a mild soap and dry them with a soft towel drying carefully between your toes. Avoid soaking your feet.
Inspect your feet and toes every day for cuts, blisters, redness, swelling, calluses, or other problems. Use a mirror—laying a mirror on the floor works well—or get help from someone else if you cannot see the bottoms of your feet. Notify your health care provider of any problems.
Moisturize your feet with lotion, but avoid getting the lotion between your toes.
File corns and calluses gently with a pumice stone. After a bath is best because they have become softer and easier to work with.
Keep your toenails cut to the shape of your toes, filing the edges with an emery board.
Always wear shoes or slippers to protect your feet from injuries. Prevent skin irritation by wearing thick, soft, seamless socks.
Make sure your shoes fit well and allow your toes to move. Wear new shoes for only an hour or so at a time, breaking them in slowly.
Make sure your shoes have no tears, sharp edges, or objects inside them that could injure your feet before putting them on.
If you need help taking care of your feet, make an appointment to see a foot doctor, also called a podiatrist.
Points to Remember
- Diabetic neuropathies are nerve disorders caused by many of the abnormalities common to diabetes, such as high blood glucose.
- Neuropathy can affect nerves throughout the body, causing numbness and sometimes pain in the hands, arms, feet, or legs, and problems with the digestive tract, heart, sex organs, and other body systems.
- Treatment first involves bringing blood glucose levels within the normal range. Good blood glucose control may help prevent or delay the onset of further problems.
- Foot care is an important part of treatment. People with neuropathy need to inspect their feet daily for any injuries. Untreated injuries increase the risk of infected foot sores and amputation.
- Treatment can include pain relief and/or other medications depending on the type of nerve damage.
- Smoking in itself causes circulatory problems which greatly increases the risk of foot problems and amputation. If you smoke, ask your health care provider for help with quitting.

Complications of Diabetes (Neuropathy) Part 2
Peripheral neuropathy is responsible for damage in the arms and legs. The lower extremities (feet and legs) are usually affected before the upper extremities (hands and arms). Often diabetics feel no symptoms. Regular diabetic appointments with your doctor are recommended because he may be able to detect signs of neuropathy that you can’t yet.
Symptoms of peripheral neuropathy include:
- numbness or insensitivity to pain or temperature
- a tingling, burning, or prickling sensation
- sharp pains or cramps
- extreme sensitivity to touch, even light touch
- loss of balance and coordination
- These symptoms are often worse at night
Muscle weakness and loss of reflexes can be caused by peripheral neuropathy. Loss of reflex at the ankle can change the way a person walks. Foot deformities, like hammertoes and the collapse of the mid-foot can result.
Having feet that are numb or have lost feeling makes it easy not to notice injuries.
For instance, a few days ago I sliced the bottom of my foot, on the ridge back of the toes. I barely felt it, even to walk on. Had I not immediately taken care of it I would run the risk of infection. The infection can then spread to the bone resulting in amputation. Not something anyone would want.
A few years ago I had a friend who was diabetic. He had an injury to his ankle and despite being under a doctor’s care infection set in. He has now had several amputations to that leg as the doctors attempt to get rid of the infection that had spread to the bone. Every time the infection has started once again in the stump.
Please take care of ANY injuries promptly and if there is ANY sign of infection get in to your doctor immediately. If you are diabetic don’t try to care for an infection yourself. Your immune system is weak and may need help to battle it. Even a very small cut, if it won’t heal, can cause a life and/or limb threatening infection.
Autonomic neuropathy affects the nerves that control the heart, regulate blood pressure, and control blood glucose levels. Other internal organs can also be affected. Problems with digestion, respiratory function, urination, sexual response, and vision can result. One may not experience the warning symptoms of hypoglycemia because the system that restores blood glucose levels to normal after a hypoglycemic episode (low blood sugar) can be affected,
I know something about hypoglycemia unawareness. I used to have definite signs of having a “low”. Shaking, sweating, nausea, weakness, and palpitations. I only had to get below a 5 to start feeling the signs. Now I don’t feel them. I am nauseous much of the time to begin with, so I no longer have that signal to rely on. The symptoms don’t happen now till I am under a 4 and usually not till I am approaching a reading of 3.5 or less.
The heart and blood vessels are part of the cardiovascular system. This is the system that controls blood circulation. Autonomic neuropathy can affect this system as well. When the nerves are damaged in this system it interferes with the body’s ability to adjust blood pressure and heart rate. Blood pressure can drop sharply after sitting or standing, making one feel light-headed or even cause one to faint. Damage to the nerves that control heart rate can make your heart rate stay high instead of rising and falling. A normal part of body function and physical activity.
Nerve damage to the digestive system most commonly causes constipation. It can also cause the stomach to empty too slowly, a condition called gastroparesis. It can cause persistent nausea, vomiting, bloating, and loss of appetite. Something I suffer from. Because you cannot digest your food properly gastroperesis can cause your blood glucose to fluctuate wildly. Damage to the esophagus can make it difficult to swallow, and damage to the bowels can cause constipation alternating with frequent, uncontrolled diarrhea, especially at night. A faulty digestive system can also cause weight loss.
Autonomic neuropathy often affects the organs that control urination and sexual function. The bladder cannot empty completely, which can allow bacteria to grow in the bladder and kidneys, causing urinary tract infections. When the nerves of the bladder are damaged, a person may be unable to sense when the bladder is full or control the muscles that release urine. Urinary incontinence, either partial or total, can be a result. Many of us, as we get older, experience some incontinence. Like dribbling when we laugh, etc. The neuropathy makes it worse, of course.
Autonomic neuropathy can also decrease sexual response, although the sex drive may not change. A man may not be able to get an erection or may climax without ejaculating normally. A woman may have difficulty with arousal, lubrication, or orgasm.
The nerves that control sweating can be affected by autonomic neuropathy too. Damage to the nerves can prevent the sweat glands from performing properly and the result is that the body cannot regulate it’s temperature properly. This damage can also cause profuse sweating at night or while eating. Something I go through on a regular basis, though in my case menopause is a factor as well.
Autonomic neuropathy can affect the eyes. The pupils become less responsive to changes in light. A person may not be able to see well when a light is turned on in a dark room because the eyes won’t adjust quickly to the change, or you could have trouble with your night vision while driving. It seems to me that my vision is not only affected when in a dark room, or for driving but, due to the fact I wear bi-focal lenses now, I have a hard time focusing or getting the correct distance from the page to use either the upper portion of my glasses, or the lower portion meant for reading. On my computer my head is at an awkward angle in order to see the screen. Often this causes eye strain, and neck strain resulting in headaches.
Proximal neuropathy, sometimes called diabetic amyotrophy, amongst other names too hard to understand, starts with pain in the thighs, hips, buttocks, or legs, normally on one side of the body and is more common in those with type 2 diabetes and in older adults with diabetes. It causes weakness in the legs and difficulty going from a sitting to a standing position without help. Treatment for weakness or pain is usually needed. The recovery period varies, depending on the type of nerve damage.
Focal neuropathy appears suddenly and affects specific nerves, most often in the head, torso, or leg.
It may cause an inability to focus, double vision, aching behind one eye, paralysis on one side of the face, (called Bell’s palsy), severe pain in the pelvis or lower back, pain in the front of a thigh, pain in the side, stomach or chest, pain on the outside of the shin or inside of the foot, chest or abdominal pain (sometimes mistaken for heart disease, a heart attack, or appendicitis.It happens mostly in older adult diabetics and is painful and unpredictable, though it does tend to improve on its own over weeks or months and no long-term damage is caused.
People with diabetes also tend to develop nerve compressions, (or entrapment syndromes). Of these the most common is carpal tunnel syndrome. Carpal tunnel syndrome is typified by numbness and tingling of the hand and occasionally muscle weakness or pain. Other nerves susceptible to entrapment can cause pain on the outside of the shin or the inside of the foot.
I think I have covered most of the effects and types of neuropathy so, at this point I would like to thank my readers for coming back. I hope you are finding the information valuable and I look forward to your comments. The next installment(s) will be addressing prevention, diagnoses and treatment of diabetic neuropathies.

Complications of Diabetes (Neuropathy) part 1
- diabetic neuropathy: the nerve damage
- heart disease and stroke
- diabetic retinopathy (diabetic eye disease)
- erectile dysfunction
- hypoglycemia (low blood glucose)
- kidney disease and failure
- sexual and urological problems
- stomach nerve damage (gastroperisis)
- liver damage
Next they poked my feet with something (a pin I think). This I could feel, indicating that the nerve damage wasn't too bad yet, but was definitely there.
Some people with nerve damage have no symptoms. Others may have symptoms such as pain, tingling, or numbness—loss of feeling—in the hands, arms, feet, and legs.
These symptoms depend on the type of neuropathy and which nerves are affected.
The first symptom is often numbness, tingling, or pain in the feet. This is often minor at first and because most nerve damage occurs over several years, mild cases may go undetected for a long time. However, for some people the onset of pain can be sudden and severe. Symptoms can involve the sensory, motor, and autonomic—or involuntary—nervous systems.
Symptoms of nerve damage may include:
- numbness, tingling, or pain in the toes, feet, legs, hands, arms, and fingers
- wasting of the muscles of the feet or hands
- indigestion, nausea, or vomiting
- diarrhea or constipation
- dizziness or faintness due to a drop in blood pressure after standing or sitting up
- problems with urination
- erectile dysfunction in men or vaginal dryness in women
- weakness
I don't have vomiting most of the time. I have constant nausea which I take another medication for. And acid reflux disease, a severe form of indigestion which I take yet another medication for. I have gone through several medications and developed a resistance to them so I have had to change every so often.
I experienced numbness, and tingling. My feet and hands go numb (what most would call "going to sleep") quite a bit, and on the side of my knee I had felt a tingling sensation, (somewhat itchy too when it tingled), for a long time. Now the area is just numb. At least on the surface. I can still feel a good poke in those areas though.
I have bouts of alternating diarrhea and constipation. The bouts of diarrhea are the worst. I can't go out of my home or be very far from a bathroom, which makes it difficult to work at times even though I only work part time, one or two days a week. When it hits, with absolutely NO warning, I need a bathroom NOW!!
If I am faced with a bout of constipation I only have problems when my system starts working again. Then I experience excruciating cramps and pain until I am able to relieve myself. Often I will go from constipation right into a bout of diarrhea. Not a whole lot of fun to say the least.
Everywhere I go, I scope out where the nearest bathrooms are. I don't go out and visit much anymore either because I find it embarrassing to be hit with a bout of diarrhea while visiting.
Nerve problems can occur in every organ system, including the digestive tract, heart, and sex organs.
Up to 70 percent of diabetics have some type of neuropathy. And it can develop at any time, though there is an increased risk the older you are and the longer you have had diabetes. The highest rates of neuropathy are amongst people who have had diabetes for at least 25 years.
Diabetic neuropathy also seems to be more common in people who have problems controlling their blood glucose, also called blood sugar, as well as those with high levels of blood fat, high blood pressure and those who are overweight. Many diabetics on insulin become overweight. A side effect of insulin is weight gain and it's a catch 22. The more weight you gain the more insulin you need, the more insulin you need, the more weight you gain.
- metabolic factors, such as high blood glucose, long duration of diabetes, abnormal blood fat levels, and possibly low levels of insulin
- neurovascular factors lead to damage of the blood vessels that carry oxygen and nutrients to nerves
- autoimmune factors cause inflammation in nerves
- mechanical injury to nerves, like carpal tunnel syndrome
- inherited traits that increase susceptibility to nerve disease
- lifestyle factors, such as smoking or alcohol use
- Peripheral neuropathy, the most common type, causes pain or loss of feeling in the toes, feet, legs, hands, and arms.
- Autonomic neuropathy causes changes in digestion, bowel and bladder function, sexual function and response, and perspiration and can affect the nerves that serve the heart and control blood pressure, nerves in the lungs and eyes. It can cause hypoglycemia unawareness as well, a condition in which people no longer have the warning symptoms of low blood glucose levels.
- Proximal neuropathy causes pain in the thighs, hips, or buttocks and leads to weakness in the legs.
- Focal neuropathy is the sudden weakness of one nerve or a group of nerves, causing muscle weakness or pain. Any nerve in the body can be affected.
Peripheral neuropathy affects:
- toes
- feet
- legs
- hands
- arms
