Iron deficiency anemia can be caused by a lack of iron in the diet, which is often seen in vegetarians who forget to find substitutes for meat and fish. In addition, a deficiency in vitamin B12, which is only found in animal products, can also lead to hair loss. However, conditions such as hyperacidity, helicobacter pylori, or ulcers can interfere with the absorption of vitamin B12.
Symptoms of a vitamin B12 deficiency include memory problems, bad mood, weakness, and poor sleep. For those who are vegetarian, vegan or have stomach problems, taking a supplement of vitamin B12 may be necessary. While there are pills available that can be sucked under the tongue for easy absorption, it is important to note that not all of it is absorbed due to large doses being needed. Excess vitamin B12 is excreted in the urine and is not harmful to the body. Taking these supplements can help prevent deficiencies that contribute to hair loss and other health issues.
