From the perspective of traditional Chinese medicine, chest tightness, disharmony between spleen and stomach, and small appetite are caused by spleen deficiency, and the problem can be solved by strengthening the spleen and stomach.

Boil porridge with 50g yam, japonica rice100g, Poria cocos10g, Euryale ferox10g, and take it at 7: 00-9: 00am, which can strengthen the spleen and regulate the stomach. If you insist on taking it, you can solve your discomfort.

If you take medicine, you can solve the problem with Jianpi Yangwei Pill.

That's my answer to your question. Thank you.
