Your body depends on nutrients to fuel every cell and organ. When absorption does not work properly, even a balanced diet may not be enough. Malabsorption occurs when the digestive system cannot efficiently process vitamins, minerals, or proteins from the food you eat. Over time, poor absorption can lead to fatigue, weakness, and noticeable health changes. Some symptoms are subtle and easy to ignore at first. Others may affect your skin, mood, digestion, or energy levels. Re
