Hiccups are caused by diaphragmatic spasm, which can be relieved by hot compresses, breath holding, deep breathing and taking medication. 1. Hot compress: If the diaphragm spasm is caused by cold, it can be relieved by applying hot compress on the abdomen or drinking warm water. 2. Breath-holding: When hiccups occur, inhale deeply, hold the breath for a period of time, and then exhale, which can also relieve diaphragmatic spasm. 3. Deep breathing: Rhythmic deep breathing can also improve diaphragmatic spasm and relieve hiccups. 4. Taking medication: If the patient has persistent hiccups, he can take baclofen, chlorpromazine and other drugs; if the patient is caused by digestive diseases, he can take metoclopramide and other drugs to relieve. If the patient has hiccups for a long time or repeatedly, it is recommended to consult a doctor in time to find out the cause of the disease and carry out targeted treatment under the guidance of a professional physician. Drugs should be taken in strict accordance with the doctor’s instructions, not self-medication, so as not to delay or even aggravate the condition.
