Problem analysis: Short-term emaciation is generally caused by some high metabolic diseases, especially malignant tumors. If there is nothing wrong with your mother during the examination, it may be because of poor gastrointestinal function, which leads to indigestion.

Suggestion: I suggest that you let your mother regulate the digestion and absorption function of gastrointestinal tract. Don't eat spicy food, don't drink, don't eat cold and frozen food. At the same time, pay attention to relax, have a good rest, and eat more high-quality protein, especially meat, eggs and milk, which is good for your health.
