Reasons for low levels of vitamin B1 in people

 Thiamine or vitamin B1 deficiency could be because of a variety of reasons.

    1. Undernourishment or malnutrition 

    Vitamin B1 is highly water soluble and it must be constantly replenished through a wholesome diet. An average human being has 30 mg of vitamin B1 in

    2. Chemical deterioration 

    The human body strives to maintain an ideal Ph balance (acid-base or acid-alkaline balance). When this balance is disrupted and/or body temperature is elevated, it leads to the breakdown of thiamine and ultimately results in vitamin B1 deficiency. Another reason for chemical deterioration is sulfites (chemical agents used as preservatives) in meat products, processed foods, etc. his body that depletes in roughly fifteen to twenty-one days. People whose diet is heavy on carbohydrates and deficient in protein suffer from vitamin B1 deficiency.

    3. Consumption of alcohol 

    Consuming excessive amounts of alcohol places undue stress on your metabolism and causes nutrient deficiencies. Not just vitamin B1, alcohol affects the absorption of vitamins B1, B2, B3, B6, B15 B12 and folic acid.

    4. Prolonged diarrhea 

    Prolonged diarrhea impairs the body’s ability to absorb vitamin B1. Severe liver disorders also have the same effect on the body’s ability to absorb thiamine.


      5. Autoimmune diseases

      Vitamin B1 is absorbed deep inside the small intestine, but the process of digestion starts in the stomach itself. Autoimmune disorders destroy the unique cells that assist in the absorption of vitamin B1. A simple visit to the doctor can reveal the cause and he will prescribe B1 vitamin supplements to solve the problem.

      6. Small intestinal bacterial growth

      Small intestinal bacterial growth is a condition wherein excessive bacteria are present in the small intestine. These bacteria use vitamin B1, B12 etc. for their own purposes, which disturb your digestive system and hinders its ability to absorb vitamins.

      7. Inflammation 

      Inflammation in the far end of your intestine can contribute to vitamin B1 deficiency. There could be several reasons for it, like Crohn’s disease, pain-relieving medications etc. Pain in the lower abdomen and diarrhea are some signs of inflammation.

      8. Tapeworms and complicated surgeries

      Tapeworms and many complicated surgeries can play havoc with your digestive system leading to vitamin B deficiencies (of all kinds). People who undergo weight loss surgeries or have a part of their small intestine removed are vulnerable to vitamin deficiency issues. They should consume supplements regularly to prevent vitamin B deficiencies.

          These are only some reasons for Vitamin B1 deficiency in adults and others. Other causes of Vitamin B1 deficiency include - anorexia, old age, nausea, vomiting and HIV/Aids.
