Does Diabetes Cause Hair Loss? Symptoms, Diagnosis, and Treatment


Diabetes is a chronic condition that occurs when your pancreas doesn’t produce enough or any insulin, or your body cannot use the glucose for energy or a combination of these two conditions.

People diagnosed with diabetes probably know that the disease can affect different parts of the body. Diabetes symptoms vary depending on which type of diabetes you have. The common symptoms of diabetes include extreme thirst, blurry vision, frequent urination, more hunger, fatigue, numb or tingling feet, weight loss, etc.

But what about hair? People with diabetes are often left puzzled with a lot of concerns like can diabetes cause hair loss too, does diabetes medication cause hair loss, how can I prevent hair loss from diabetes meds, will hair loss from diabetes grow back, can insulin resistance cause hair thinning, and many more.

This article will explore the connection between diabetes and hair loss, including common causes, treatments, etc.

Can Diabetes Cause Hair Loss?

Does diabetes cause hair loss? This is one of the most asked questions by people.

High blood sugar levels and complications associated with diabetes can lead to hair thinning, hair fragility, or severe hair loss in some people.

Diabetes and hair loss are linked due to various causes like immune system disorders, elevated blood glucose levels, side effects of diabetes medications, etc. The normal hair growth cycles may get interrupted when glucose levels in the blood are out of range.

Can insulin resistance cause hair thinning? It is a major concern of people with diabetes as it is a symptom associated with diabetes. Insulin resistance is known to cause hair loss and hair thinning. Resistance to the hormone insulin can cause an increase in blood sugar levels and increases your risk for developing prediabetes and type 2 diabetes.

According to a 2014 study, researchers found links between Androgenic Alopecia, also known as male-pattern baldness, and insulin resistance.

Causes of Hair Loss Problem in People with Diabetes

Hairloss and diabetes

Hair loss in a person with diabetes can occur for a number of reasons, but the most common causes include those below.

High Blood Glucose Levels

If you have diabetes left uncontrolled or untreated, it means your blood sugar levels are too high. The high sugar levels in the blood can cause serious health problems. Moreover, persistently elevated glucose levels in the bloodstream for a long time can damage many blood vessels, organs, and tissues of your body.

Damage to blood vessels can limit blood flow to certain cells, which leads to less oxygen and fewer nutrients reaching the hair follicles than needed. This will negatively impact the hair growth cycle and lead to hair thinning and hair loss.

Thyroid Issues

People who have diabetes are at increased risk of developing some form of thyroid disorder. Therefore, if you have diabetes, you should get your thyroid checked at least once a year to ensure that you aren’t developing hypothyroidism or hyperthyroidism.

Especially, patients with type 1 diabetes are more likely to have co-occurring autoimmune thyroid diseases. If you have a severe thyroid condition and left it untreated, it may lead to hair loss because disruptions in the thyroid hormone can affect the hair cycle.

So it is advised to check and treat thyroid if you have.

Hormonal Imbalance and Stress

The physiological and psychological stress of living with a chronic illness like diabetes can affect hair growth because persistent stress can cause hormone fluctuations, leading to hair loss.

Alopecia Areata

People with diabetes are more likely to develop an autoimmune disease called alopecia areata. This condition occurs when the immune system attacks hair follicles, which cause hair to fall out in small circular patches from the head and other parts of the body.

Medication Side Effects

Certain medicines you take to treat your diabetes can interrupt the regular hair growth cycles, leading to hair thinning and slowing down your hair growth.

Does metformin cause hair loss? It is a commonly asked question as it is the first-line medication used for the treatment of type 2 diabetes. Even though metformin is not a known cause of hair loss, long-term use may increase the risk of vitamin B-12 deficiency, which can sometimes contribute to hair loss.

Symptoms and Diagnosis of Diabetes Hair Loss

Hair loss is one of the most common problems experienced by everyone at some point in their lifetime. It can appear in several different ways and can affect just your scalp or your entire body, depending on what is causing it.

For instance, if you experience sudden hair loss in small patches and are diagnosed with type 1 diabetes, you may have developed an autoimmune disorder known as alopecia areata. Moreover, people with diabetes are also more prone to getting skin disorders such as itching, bacterial infections, and fungal infections.

Your dermatologist can determine the cause of your hair loss through proper diagnosis.

To determine the cause of your hair loss, your dermatologist asks various questions about when hair loss began, whether your hair falls out in patches or clumps, whether it is sudden or gradual hair loss, and other details about your symptoms. Based on your medical history and physical examination, doctors can recognize whether the reason is genetic, medical, or environmental.

In addition, the factors like stress levels, other health conditions, medications, etc., will also be considered for accurate diagnostics. Blood Tests, Pull Tests, Scalp Biopsy, and Light Microscopy are some of the diagnostic tests performed to help pinpoint the connection between your diabetes and hair loss.
