Dr Swathi Reddy (PT), Consultant Physiotherapist and certified diet counselor and MIAP, Motherhood Hospitals, Bengaluru, spoke to Health Shots about the vitamin D deficiency causes and the factors that can block the absorption.

Dr Reddy says, “Vitamin D is extremely essential as it helps your body absorb calcium, fight infection, and also helps your muscles work properly. The best source of vitamin D is sun exposure, but usually, people do not spend enough time in the sun to get adequate amounts of vitamin D, therefore it is recommended to supplement it with food as well.”

What blocks the absorption of vitamin D?

There may be certain conditions and things that affect your ability to absorb vitamin D. Figuring out what factors are affecting your vitamin D absorption capacity can help you take the right treatment to solve the issue.

Here’s what makes vitamin D absorption difficult, according to Dr Reddy:

1. Poor gut health

Vitamin D that you get from food items or supplements is absorbed in the part of the small intestine which is immediately downstream from your stomach. The absorption of vitamin D depends on the stomach juices released, bile from the liver, secretions from the pancreas, the integrity of the wall of the intestine, etc. When these factors are affected due to health conditions like celiac disease, chronic pancreatitis, Crohn’s disease, and cystic fibrosis, your vitamin D absorption reduces.

2. Liver issues

Vitamin D deficiency is quite common in patients with liver diseases. Even if a person suffers from a mild liver condition, they will have some degree of vitamin D insufficiency. Patients with liver cirrhosis can suffer from severe deficiency.

3. Kidney issues

The kidneys play a crucial role in ensuring the proper absorption of vitamin D for the body. If a person suffers from kidney disease, there is a high chance their vitamin D levels will be low. Injured kidneys will not be able to convert enough vitamin D into its active form calcitriol, which is used throughout the body.
