Other causes of Vitamin D Deficiency that you should be aware of

A lack of being in the Sun may often steal your fun, but there is also a list of other causes that may lead to chronic Vitamin D Deficiency. We have tried to summarize some of these according to the latest research in the field.

Have a read and understand the complexities of the human body.


Obesity is no longer a silent killer. It is an endemic attributed to our careless attitude and fast paced lifestyle. The human being has evolved to store the Vitamin D produced in Fat so we can have ample stock when there is little or no sunlight especially during cold winter months. However, we haven’t evolved to carry large deposits of fat in our body and this is when our metabolism goes down and hormones get imbalanced.

Obese people have lower levels of Vitamin D since the excess fat absorbs the Vitamin D for storage and therefore, cannot access this stock.

Obesity Surgery

In mid 2009, a research study by the Mayo Clinic was published indicating that ‘Obesity surgery May Thin Bones, Cause Breaks, Bariatric Patients May Be More Likely to Fracture Hands or Feet’.

Recent studies indicate that a year after the gastric bypass surgery, hip density among adults drops by as much as 10 percent. Compared to Gastric Bypass, Stomach banding causes less thinningsince it doesn’t alter the way the body absorbs nutrients. However, Gastric Bypass makes it tougher to absorb calcium. Despite losing the fat, Vitamin D levels do not rise because the change in the transit time of food through the digestive tract adds another hurdle to the body’s ability to absorb Vitamin D from the diet. Same is the case for the absorption of other nutrients in the body.

Chronic Kidney Disease

This condition is more common in people with hypertension and is hardly diagnosed until it has reached later stages. It is recommended you talk to your family doctor about it and receive appropriate Vitamin D supplementation to maintain a blood level of 25-Vitamin D of at least 30 nanograms per millilitre; a blood level of upto 100 nanograms per millilitre is considered to be safe.

Antiseizure Medications

People who are on antiseizure medications especially the ones to treat epilepsy have a far worse Vitamin D level than others. Drugs used to treat epileptic seizures destroy 25-Vitamin D making them more prone to develop rickets or other Vitamin D deficiency related conditions.


Prednisone is steroid used as an anti-inflammatory, anti-allergic medicine and is used to treat a variety of conditions especially in patients suffering from hypertension. However, it destroys 25-Vitamin D in the body meaning that those taking prednisone should be treated with higher doses of Vitamin D through effective supplementation.


People who have had organ transplantation done or those who suffer from AIDS need double the dose of Vitamin D in their bodies since they are on immunotherapy.

St. John’s wort

This popular herbal supplement is reported to destroy 25-Vitamin D in the body. Although, it may act as a brain booster, it can affect your body’s ability to absorb Vitamin D.


Those taking Orlistat marketed as Alli or Xenical decreases the body’s ability to absorb dietary fats thereby leading to reduce the absorption of Vitamin D in the body.


It is used to treat cholesterol and may interfere with the absorption of Vitamin D in the body.

Fat Malabsorption Syndromes

People who are unable to absorb fat in their body due to a variety of conditions including pancreatic enzyme deficiency, Crohn’s disease, cystic fibrosis, celiac disease, liver disease, stomach surgery and small bowel disease.

Kidney Failure

As you have read earlier it takes a healthy kidney to activate Vitamin D in the body. Those who are on dialysis or suffer from kidney failure need to increase their daily intake of Vitamin D.

Eating disorders

Those suffering from anorexia or bulimia score low on bone density and may have low levels of Vitamin D in their body.

Liver Failure

Liver failure decreases the production of 25-Vitamin D and also makes it difficult for the intestine to absorb fat.

Primary Biliary Cirrhosis

Here, the bile ducts are destroyed making it difficult for the bile juice to reach the intestine which assists in the absorption of Vitamin D.

So, stay aware and don’t skip your daily dose of Sun. Have fun.
