2. Schizophrenia: When schizophrenia is not treated in time, with the development of the disease and the influence of external adverse stimuli, some patients develop into severe schizophrenia. Patients with severe schizophrenia will have aggressive behavior and hallucinations, which will make them suffer a lot, and in severe cases, they will attempt suicide or hurt others.
3. Anorexia nervosa: These patients refuse to eat due to the excessive pursuit of a slim figure, which can lead to serious endocrine disorders and severe malnutrition. Anorexia nervosa patients also suffer from long-term malnutrition, resulting in bone mineral density below the normal range, and in severe cases, hypoproteinemia, which is a life-threatening condition.
