Diseases that Cause Hair Loss (Part 2)

Celiac Disease

Celiac Disease and Hair Loss

Celiac disease, also called celiac sprue, is a digestive system disorder caused by an immune reaction from eating gluten, a protein found in wheat, barley, rye, and oats.

Although gluten is harmless to most people, in the case of celiacs, it destroys the lining of the small intestine, reducing its ability to absorb nutrients.

If the intestine cannot absorb nutrients well, the entire body suffers, including hair. People who suffer from this condition also suffer from hair loss because the hair needs nutrients, vitamins, and minerals to grow strong and healthy.

There is no cure for celiac disease. However, following a strict gluten-free diet can help minimize symptoms and help the intestine heals.  


Dandruff is not a contagious or an infectious disease but is one of the diseases that cause hair loss. Not so directly, though.

The condition impacts roughly 50 percent of people worldwide, so you're not alone with this issue if you are suffering it.

This skin illness can cause the scalp to flake and even swell with redness. It can also make your scalp feel dry and itchy.

That itchiness would result in the urge to scratch, and if this happens, it will harm the hair follicles. It leads to hair loss or thinning, even though maybe it won't be a total loss.    

Additionally, dandruff may increase hair loss in people with androgenic alopecia, a state which creates male and female pattern baldness.

It would be awkward to see us with less or no hair, which can translate to any individual not looking or feeling attractive. Of course, it would also hurt our self-esteem.


Diabetes is a disease that occurs when someone has high blood glucose levels. There are two kinds, type 1 or 2. Type 1 is an autoimmune disease.

What does that mean? The one who has it is likely to develop a condition called alopecia areata, in which the white blood cells attack the hair follicles instead of protecting them as it is supposed to be. 

To read more on why diabetes appears on the list of diseases that cause hair loss, read the article: Diabetes and Hair Loss.


Pains and tension or stress are related to hair loss. Therefore, if we say there is a connection between stress and hair loss, the same happens to headaches, especially tension headaches.

You can go directly to the article: "Hair Loss and Headaches" if you need a complete explanation of why headaches are linked to stress and hypothyroidism, therefore to hair loss.  


Lupus is another disease that causes hair loss. Although Lupus itself is not contagious, it can cause damage to the organs of the body and pain and complications in the skin. 

Some of these complications cause permanent hair loss if they don't take the appropriate measures. There are four kinds of Lupus:

1.  Systemic Lupus Erythematosus or SLE-It is a class of Lupus that affects different body organs. It is difficult to detect because there is no specific study that does.

2.  Discoid Lupus Erythematosus-This type of Lupus causes a chronic irritation in the form of discs, especially on the scalp. Hence its name Discoid Lupus. When irritation occurs, scars form like discs. Once hair is lost, it does not grow back.

To see the relationship between this disease and how that affects your hair, read the article: Discoid Lupus and Hair Loss.

3.  Subacute Cutaneous Erythematosus-This type of Lupus forms sores and inflammation in the skin, when the one that has it is exposed to the sun.

4.  Drug Induced Lupus-The name says it all. It is a type of Lupus caused by drugs or medications.

Those are the four kinds of Lupus, which is part of the diseases that cause hair loss. Lupus makes the hair on the scalp thin, although only a few lose significant amounts of hair. For a complete understanding of Lupus, go to Lupus and Hair Loss article.

Discoid lupus forms discs with a rash, causing hair loss in those areas, but where the scar forms, hair does not grow back if not treated early.

It's like when you put a branding iron on the cows to identify them. Where it is marked, hair doesn't grow back, and therefore hair loss becomes permanent.

Similarly, if Discoid Lupus doesn't get timely treatment, it has the same effect on the scalp. It cannot recover when the hair is lost, and the scars form. That's why it's essential to see your doctor as soon as you notice any symptoms.
