Vitamins And Minerals Deficiency Diseases

Diseases Caused By Deficiency Of Vitamins And Minerals

What Is Vitamin And Mineral Deficiency?

Vitamins and minerals are essential nutrients that your body needs in trace amounts. These are required for almost every process in your body to function normally. A few vitamins include vitamins A, C, D, E, K, and the B group of vitamins and minerals such as calcium, magnesium, phosphorus, potassium, sodium, and iron.

Some important functions of vitamins and minerals include wound healing, strengthening the immune system, converting food into energy, maintaining healthy bones, and promoting healthy teeth.

The vitamins and minerals are obtained from dietary sources. A vitamin or mineral deficiency occurs when your body fails to get them in adequate amounts. People who follow a poor diet, eat low-quality foods, or fail to take supplements if required are at an increased risk.

A deficiency is detected in blood tests when patients get tested on experiencing the related symptoms. Once detected, vitamin and mineral deficiency is addressed by following a healthy diet containing the required nutrients or through supplements. Severe cases may require IV infusions to replenish the missing nutrients. Diseases caused by the deficiency of vitamins and minerals include visual and skin changes, bone health issues, anemia, neurological problems, and blood clotting problems.

  • Excessive alcohol intake
  • Certain medications such as proton pump inhibitors (PPIs)

It is good to get your vitamin and mineral levels checked, especially if you have symptoms or health risks of nutritional disorders.

Nutrient deficiency diseases are diagnosed through blood tests like;

A Venous Blood Test

The blood sample is obtained using a needle to puncture a vein, usually in your arm.

A Finger-prick Blood Test

The blood sample is collected by pricking your finger using a lancet
