The manifestations of protein deficiency in women may include edema, malnutrition, low immunity and indigestion. 1. Edema: under normal circumstances, albumin can maintain the body’s osmotic pressure, protein deficiency will lead to a decrease in the body’s colloid osmotic pressure, resulting in fluid accumulation in the tissues and thus manifested as edema. 2. Malnutrition: Protein is involved in the composition of human muscles and hair, when protein deficiency will lead to people’s muscle atrophy, hair loss. 3. Low immunity: the antibodies in people’s body are mostly composed of protein, when protein is lacking, the synthesis of antibodies in the body is insufficient, which will lead to low immunity and therefore easy to be infected. 4. Indigestion: Protein is also involved in the formation of some of the body’s digestive enzymes, so the lack of protein can also lead to indigestion.
