Does Diabetes Cause Nail Fungus

Frequent Itchy Red Spots

Why Do Diabetics Get More Fingernail and Toenail Fungus?

A lesser-known symptom of fungus overgrowth is skin rashes. Fungus can cause red, scaly, or itchy patches anywhere on the body, but often sticks to areas prone to dampness, such as the feet, between folds of skin, or between joints such as the knees, elbows, and underarms. These may seem like common rashes, but a rash typically reveals a deeper problem within the body, and can indicate a significant overgrowth of yeast or fungus.

Using Nail Polish While Infected With Toenail Fungus

Most treatments that are undertaken to clear the toenail fungus need access to the nail bed and under the nail as much as possible. Your goal is to get the treatment to the fungus so it can kill the fungus. Covering nails with fingernail polish will probably lessen your chances at getting directly to the fungus. Knowing this, you can still opt for using nail polish, but your results might not be as favorable as you want.

Toenail Onychomycosis In Diabetic Patients: Issues And Management

Abstract Diabetes mellitus may be associated with serious sequelae, such as renal disease, retinopathy, and diabetic foot. A recent large prospective study has shown that onychomycosis is among the most significant predictors of foot ulcer. As the severity of onychomycosis may be associated with the length of time the individual has had the infection, early intervention is advisable owing to the progressive nature of the fungal infection. If left untreated, toenails can become thick, causing pressure and irritation, and thus act as a trigger for more severe complications. In the treatment of onychomycosis, compliance and drug interactions are important considerations, as diabetic patients frequently take concomitant medications. Terbinafine and itraconazole have been investigated for the treatment of onychomycosis in diabetic patients and have been shown to have efficacy and safety profiles comparable to those in the nondiabetic population. Data from clinical trials and postmarketing surveillance suggest that drug interactions resulting in hypoglycemia may not be an important issue when itraconazole and terbinafine are used to treat diabetic patients receiving concomitant hypoglycemic medications. Patient advice and education in improved foot care are an integral part of onychomycosis management, and help achieve long-term cure and reduce the complications of diabetic foot.Continue reading > >

Nerve Damage And Injuries

35 Home Remedies for Toenail Fungus Treatment

Diabetes often causes nerve damage. As a result, a diabetic may not feel pain or notice an injury right away. If a person with diabetes injures their toenail, they may not notice it right away or at all. For many fungal infections, an injured toenail is all it takes for the fungus to take root.

When such an injury takes place, it’s possible to catch the infection early on and prevent the fungal infection in the first place. But if you don’t notice the injury, it’s more likely for the nail fungus infection to occur and spread.

Some people with diabetes may have a couple of extra hurdles to jump over other than nerve damage when it comes to noticing the injury or infection. Diabetes can also affect a person’s vision in what is called diabetic eye disease. Obesity is another issue associated with type 2 diabetes. If a diabetic struggles with obesity, it is possible they may not be able to see their feet or get to them easily.

    This infection is not caused by diabetes, but is more common in diabetics.

    When its chronic, the damage to the cuticle can lead to a distortion in the underlying nail tissues.

    This will then cause a space that is vulnerable to infection.

    One of the microbes that can infect this space is called Pseudomonasaeruginosa.

    It is this microorganism that has the potential to give the nail an almost black color.

    Another microbe, Fusarium, can cause a blackish patch in a toenail.

    Black toenails in a diabetic can happen when the foot has suffered a lack of oxygenated blood and necessary nutrients, says J. Mark Anderson, MD, DABFM, of Executive Medicine of Texasand who is board certified in family medicine.

    This causes the toenail to die, adds Dr. Anderson. While red can be a sign of acute infection, brown and black are often a sign of permanent damage.

Untreated, toenail onychomycosis can become painful and even cause permanent damage to your nails.

Good foot care is a vital part of good health care for every diabetic.

    Neuropathy And Poor Circulation: A Bad Combination For Those With Diabetes

    Yellow toenails and diabetes

    Those with diabetes often have neuropathy or nerve damage. This condition causes loss of sensation in the extremities like the legs and especially the feet. With reduced sensation in the feet, a small injury like a bruise, cut or puncture can quickly worsen into a serious problem before you feel or notice it.

    Another problem for those with diabetes is poor circulation. Diabetes causes excess sugar complexes and plaque in the blood as well as inflammation, so the blood vessels narrow and the blood flow decreases. These factors combine to cause poor circulation in the extremities, especially the feet and legs, which can hinder healing.
