Deficiencies occurring because of a vegan diet can appear quietly
. Before symptoms are noticeable, the body feeds on its vitamin stores in areas such as the liver and fat cells. If all these sources are exhausted, deficiency symptoms
begin to occur. The symptoms can be very different depending on which nutrients you are lacking in your body. These symptoms frequently appear: Fatigue and exhaustion Mood swings with a tendency to depression Loss of appetite or an increased appetite Muscle pain Brittle hair and nails Decreased physical endurance Dizziness
However, these symptoms do not necessarily have to be caused by a vegan diet and, in many cases, have other causes as well. If you, as a vegan, are fearful of nutrient deficiencies, you should have your blood tested
Women during pregnancy and lactation, children, and seniors with limited absorption capacity are especially affected by deficiency symptoms caused by a vegan. Nutritionists advise these risk groups
against having a purely vegan diet.
