Malabsorption is a condition where the body cannot properly absorb nutrients from food in the digestive system. This can lead to deficiencies in essential vitamins and minerals, resulting in various health issues. Common causes of malabsorption include conditions like celiac disease, Crohn's disease, and infections. Symptoms of malabsorption may include diarrhea, weight loss, and bloating. Diagnosis often involves tests to evaluate the digestive system and nutrient levels. Treatment typically focuses on managing the underlying cause and may include dietary changes or supplements to ensure adequate nutrient intake.
