Vitamin D Deficiency Symptoms

What are the symptoms of Vitamin D deficiency?

The level of Vitamin D in the body cannot always be kept balanced just by taking a healthy and balanced diet. Note that only 10% of the vitamin D the body gets from food, while the remaining 90% is obtained from direct sunlight. Even if you eat foods rich in vitamin D, you are still at risk of vitamin D deficiency because vitamin D cannot be supplied in the body through diet alone.

If your lifestyle and routine is such that you are not able to take sunlight, then you may feel the following symptoms.

Be sad

Being depressed or feeling irritable are signs of vitamin D deficiency.

Gaining weight

If you suddenly become obese or you gain weight, it means that there is a deficiency of Vitamin D in your body. The special thing is that people who are overweight have a higher need for vitamin D than people who are underweight. If you are overweight because of your muscle mass, you may still need to take more vitamin D, as vitamin D is a fat-soluble vitamin.

Being vulnerable to frequent infections

You should know that vitamin D strengthens your immunity. When your immune system is strong, it helps you fight off bacteria and viruses.

Feeling more tired

Although there can be many reasons for feeling tired, but lack of vitamins also causes fatigue.

Inability to heal wounds easily

The delay in wound healing after an operation and injury is also a sign that there is a significant deficiency of vitamin D in the body.

Lack of bones

Vitamin D is really essential for the properly absorption of calcium. If the bone density is decreasing in your body, it means that there is a lack of calcium in your body. Calcium deficiency easily increases the risk of fractures.

Digestive trouble

Vitamin D is a type of fat-soluble vitamin. Any type of digestive disease affects the absorption of fat, which also leads to low levels of vitamin D.

Pain in bones and joints

Vitamin D deficiency affects bone health. Along with this, due to lack of vitamin D, there is also pain in the bones. This pain is really felt more on the knees and back. Apart from this, due to deficiency of vitamin D, the risk of osteoporosis, a type of bone disease, bone pain and easy fracture increases significantly.

Head sweating
