Why people with diabetes are more prone to infections

We have been so far understood that chronic diabetes can at times be dangerous for all the vital organs of the body, such as kidneys, eyes, etc. Interestingly, a team of researchers from the California State University, conducted a study, wherein more than 1,00,000 patients were analyzed for the detrimental effects of their chronic diabetes. The results obtained were quite surprising, further suggesting that people with diabetes are more prone to infections. Let’s further see how?



Diabetes is identified to be one of the most prevalent diseases in every nook and corner of the world. It is characterized by the increase in blood glucose level and a decrease in the cellular metabolism; either due to the absence of insulting or degeneration of insulin-producing beta cells. Investigations done so far, have proven that although diabetes seems to be a silent disease, it is quite prone to infections.  Chronic exposure to the blood glucose level can lead to malfunctioning of various organs.

And hence, people with diabetes are being identified to increase the susceptibility of various infectious diseases, the details of which are mentioned further.

Infections associated with diabetes

As mentioned earlier, poorly controlled diabetes and continuous consumption of steroidal medications are responsible for a number of infections, mentioned herewith:

Ear, Nose and Throat Infections

Throat infectionAlmost 70% of patients with diabetes have reported malignant infections, such as otitis externa as well as rhinocerebral mucormycosis. These infections are associated with bacterial growth in the external auditory canal that may progressively spread to other softer tissues, such as cartilages, bones, etc. Experts have suggested that these infections may result due to poor hygiene and lack of maintenance of proper blood sugar diabetic patients. Studies have evaluated that these organisms can grow in multiple colonies and pass through other softer tissues through different blood vessels.

Urinary tract infections

Urinary tract Diabetic patients are also prone to infections, such as urinary tract infections; possibly due to the increased risk of bacterial multiplications such as pyuria, cystitis etc. Diabetic patients, who are also suffering from pyelonephritis lose control over their diabetes, especially due to increased insulin resistance. People with diabetes may have a nauseatic feeling and hence may face difficulty in maintaining proper hydration. Although, it should be noted that many of these ailments if sugar is being considerably controlled through proper nutrition.

Infections of skin and soft tissues

skin-infectionPeople with diabetes are also prone to infections of the skin, sensory neuropathy, and atherosclerotic vascular diseases. In fact, several studies have indicated that skin and soft tissue infections are more common in chronic diabetics, of age more than 35 years. More commonly reported manifestations are a diabetic foot and other infections of feet.

Bullosis diabeticorum is commonly reported infection of acral skin in many chronic diabetics. However, blisters that are prevalent in this type of skin diseases may generally heal within less period of time.


OsteomyelitisSkin ulcers, particularly poly microbial infections associated with chronic ulcers can spread to surrounding bones underneath. The disorder is known as osteomyelitis. Multiple studies have been carried out in this regard. One such study indicated that around 68% of people with diabetes reported diabetic foot ulcers due to chronic diabetes.

Unfortunately, when cultures from superficial skin infections tested for causative organisms; Staphylococcus was found to be quite prevalent.

Other infections

bacteria Many chronic patients with diabetes have commonly reported skin ulcer due to the contagious spread of bacteria and poor hygiene. The indication if left untreated for a longer period of time may affect adjacent bone of the skin underneath. Other infections, that have been reported are staphylococcal infections, Klebsiella infections, pneumococcal infections, etc.

Why these infections are riskier in people with diabetes?

people with diabetes are more prone to infectionsPeople with diabetes are generally suffering from compromised immunity and hence are more prone to infections than other people. Studies have indicated that diabetics suffer from altered pH level due to elevated blood sugar levels, which is the leading cause of facilitating bacterial growth. It is also very interesting to note that patients, who have been hospitalized due to necessarily have higher mortality rates, but they do suffer from fatal infections that need urgent medical attention.

What can be done to avoid infections?

blisterCareful inspection of feet and hands is critical to avoid issues related to the infections. Minor bumps and scratches should be avoided especially by people who are more prone to infections. The examination of feet should be carried out daily for any blisters, cuts, sores and other skin problems. Other infections like urinary tract infections, infections of ear, throat etc. can be avoided by maintaining proper hygiene, practicing proper toilet mannerisms etc.

Bacterial vaginal infections are common in women due to excessive bacterial growth in the vagina, which can further increase the chances of sexually transmitted diseases.

How proper feminine health can be maintained?

Lactobacillus Women, who are more prone to infections can keep their diabetes maintained to avoid multiple attacks of infections. Accordingly, women can further reduce the complications by implementing certain precautionary measures, such as:

  • Intake of Lactobacillus acidophilus through curd and over the counter supplements can be helpful for people with diabetes to ward off other bacterial infections. In the case of women, this can also facilitate the promotion of vaginal acidity to reduce the risk of infections.
  • It should be noted that people who are more prone to infections should always maintain good hygiene by keeping their genitals clean and dry.
  • Women should always avoid douching to prevent the growth of bacteria along the vaginal lining and further protect against infections.
  • People with diabetes should keep themselves hydrated by drinking more water. This will help them to prevent drying of their genitals and skin. 

Diagnosing and treating infections

blood testOne or more tests can be performed to diagnose infections associated with chronic diabetes, which may include blood tests, body secretions as well as urinary analysis. Many expert health care providers may prescribe oral as well as topical antibiotics, which can treat many fatal infections. Proper weight management, maintenance of hygiene and the implementation of proper safety procedures can help prevent infections and promote faster healing.

This may further prevent complications of people with diabetes and help maintain their high blood sugar at a prescribed level.
