Can Diabetes Cause Itching All Over Body

Must read

How Diabetes Affects Skin

Can menopause cause itching all over?

Diabetes can have an impact on the health of skin in multiple ways. High blood glucose levels are behind most of the skin problems caused by diabetes. Too much sugar in the blood prompts the body to pull fluid from cells in order to produce enough urine to remove the sugar, which in turn makes skin dry .

Dry, red, and irritated skin also can result from damage to nerves , particularly nerves in the legs and feet. Damaged nerves may not get the message to perspire, and perspiration helps to keep skin moist and soft.

In turn, when skin is overly dry, it can crack, peel and become itchy. Scratching it can create small openings in the skin. These openings provide easy access for infectious organisms to get under the skin, where excess sugar in the blood provides a fertile breeding ground for them to proliferate.

Beyond dryness and infections are an array of other skin problems associated with diabetes.

Barely Scratching The Surface

Aaron I. Vinik Barely Scratching the Surface. Diabetes Care 1 January 2010 33 : 210212.

Itching or pruritus is an unpleasant sensation that evokes the desire or reflex to scratch. Itching in people with diabetes for the most part suggests a skin condition such as psoriasis, eczema, sunburn, athlete’s foot, hidradenitis suppurativa, pruritus vulvae from monilial infections, xerosis and diabetic eczema, necrobiosis diabeticorum, allergies to medications, drug eruptions, and many other conditions. Most are inflammatory disorders. In addition, there are generalized medical conditions that need to be excluded such as obstructive jaundice , polycythemia that can cause generalized itching, myxedema, hypoparathyroidism, uremia, iron deficiency anemia, and malignancy or systemic internal cancers such as lymphoma or Hodgkin’s disease . When all have been considered and excluded, the question that needs to be answered is, Does the itching derive from a peripheral or a central mechanism?

Interactions Between Itch And Pain: Pain Inhibits Itch

Counter-irritation has often been used to decrease pain perception. It is often used clinically, e.g., the application of capsaicin that induces pain only to desensitize and relieve it. However, it appears that the sensation of itch can be reduced by many painful sensations. Ward et al. reported the effects of noxious and nonnoxious counter stimuli, such as heat, physical vibration, or chemical stimulation on skin, were studied in healthy adults after they had experimentally induced itch and pain in their skin. They found that when they induced nonnoxious counter stimuli, the reduction of pain and itch only lasted for up to 20 s. However, when they induced noxious counter stimuli, there was a significant inhibition of itch for an extended period of time but no inhibition of pain. In addition, it was found that brief noxious stimuli created an anti-itch state for more than 30 min. These findings show that itch is not a subliminal form of pain and that noxious counterstimulus is likely to act through a central mechanism instead of a peripheral one . Thus, noxious heat and scratching have an inhibitory effect on itch , but this needs to be demonstrated in diabetic polyneuropathy.

What Does A Diabetes Rash Look Like

Diabetes rashes look different depending on the type and cause.

Some diabetes rashes only affect people with diabetes. They usually go away when blood sugar is under control. These rashes include:

  • Blisters : Painless blisters may form on the backs of hands and feet and on the legs and forearms. This rare condition most often affects people who have diabetic neuropathy.
  • Diabetes dermopathy: Light-brown, round-shaped scaly patches, like age spots, appear on the shins. These harmless spots dont need treatment.
  • Digital sclerosis: Some people with Type 1 diabetes develop hardened, thick, waxy skin on the backs of their hands. The finger joints stiffen, making movement difficult. A related rash is scleredema adultorum of Bushke which is tightness, thickening, and hardening of the back, neck, shoulders and face. There are various treatments that dermatologists can provide for this.
  • Necrobiosis lipoidica diabeticorum : This lower leg rash is more common in women. NLD causes raised, red, shiny patches with a yellow center. Blood vessels may be more noticeable. The rash may be itchy and painful. You should see a dermatologist for treatment options.
  • Diabetes Foot Syndrome: These are ulcers that develop from trauma to the skin. The ulcers can take a long time to heal and there is an increased risk for infection.

Other conditions can affect anyone, but are particularly common among people with diabetes. These rash-causing conditions can also be a warning sign of pre-diabetes:

Poor Circulation Could Be Causing Problems

If your lower legs are swelling and itchy, you might have a form of eczema called stasis dermatitis, which is caused by poor circulation, says Dr. Feely. A doctor can help you identify the underlying cause, which may include high blood pressure, varicose veins, or a systemic condition, per the AAD. Leg elevation, compression stockings, topical corticosteroids, and potentially even surgery can also help ease your itching, says Dr. Feely.

Treating Fungal Infections In People With Diabetes

A fungal infection is not something that will simply go away on its own. Youll likely find the itchiness and burning so unbearable, youll be desperate for treatment.

Here are three guidelines for managing a fungal infection:

Improve your blood sugar levels

Using medication to treat the area affected by fungus growth will only do so much if your blood sugars are still persistently high. You need to address your blood sugars. If they continue to be high, you will likely continue to face fungus issues.

Unless your high blood sugars were a temporary issue you had to endure , you should call your diabetes healthcare team immediately to adjust your medications and reduce your blood sugars as quickly as possible.

Get the right medication for the right type of fungus

You may need to consult a dermatologist or your local pharmacist to be sure youre using the right anti-fungal treatment option for the type of fungus youre dealing with.

Treatments for yeast infections are fairly obvious , but more severe yeast infections may require a visit to your gynecologist and a prescription-strength treatment option.

There are topical ointments, capsules to swallow, suppositories, lotions the list goes on and on so you need to make sure youre using the right treatment for the right type of fungal infection.

Improve your self-care skin habits

Does Itching Have Anything To Do With Diabetes

Diabetes is a condition that affects the whole body, and there is a definite connection between blood-sugar levels and itchy skin.

Why that might be is slightly complicated, in that different side-effects of diabetes cause itchiness for different reasons! Here are the three main causes of itchy skin in diabetes:

1. Most seriously, uncontrolled diabetes can cause damage to the nerves, which can manifest as itchy skin, so dont delay in getting any itchiness checked out by your diabetic team.

2. Diabetics are also more prone to dry skin, as high blood sugars draw moisture from the body. Dry skin can end up feeling itchy, as a damaged skin barrier means youre more sensitive to irritants.

3. And lastly, diabetics are more vulnerable to infection than non-diabetics.

Both bacterial and fungal infections of the skin can mean infernal itchiness, plus some viral infections can also cause rashes on the skin.

What can you do?
  • Have regular check-ups with your diabetic team
  • Treat your skin with extra care: moisturise regularly with an oil-rich emollient
  • Steer clear of irritants which can cause more damage: perfumes, sulphates , harsh preservatives, etc.
  • Use soap-free washes or bars: soap is renowned for stripping natural oils from the skin
  • Keep baths short and warm, not long and hot
  • Manage your blood-sugars as well as possible

Sensations Associated With Scratching

How to manage continuous itching over the body? – Dr. Rashmi Ravindra

Pain and itch have very different behavioral response patterns. Pain evokes a withdrawal reflex that leads to retraction and is therefore a reaction trying to protect an endangered part of the body. Itch creates a scratch reflex that draws one to the affected skin site . It has been hypothesized that motivational aspects of scratching include the frontal brain areas of reward and decision making. These aspects might therefore contribute to the compulsive nature of itch and scratching . It is clear, therefore, that itching is not skin-deep.

High Blood Sugar And Your Skin

In serious cases, high glucose in the blood can set off an immune system response and release cytokines into the bloodstream. These cytokines are associated with inflammation and can lead to itchiness in diabetics, just as they can affect people with eczema or viral rash.The worry is that diabetics with itchy skin are at risk of nerve damage, so if youre diabetic and get itchy, please do check in with your diabetic team!Diabetes are also more at risk of dry skin, and that in itself can cause itchiness. High blood sugars pull fluid from the body and the skin loses the moisture it needs to repair its defences. A compromised skin barrier will lead to further moisture loss, damage and cracked skin. And that, in turn, leaves the skin more open to infection and external irritants which can cause inflammation and itchiness.

Its a vicious circle of dryness, damage and itch!
