Burping is actually a product of human evolution and a protective response of the body. Between the chest and the abdominal cavity, there is a muscular membrane called the diaphragm, which is thick and like a hat, separating the chest and the abdominal cavity. The diaphragm also has nerve distribution and blood supply. Once stimulated, there will be paroxysmal and Spasmodic contractions, and then there will be hiccups. So what is the cause of old hiccups? Let's get to know.

What is the cause of old hiccups

1. anxiety

Anxiety can also cause hiccups on weekdays, because when you are in a state of mental stress, the body's need for oxygen increases. As a result, it will mechanically suck a lot of air into its mouth like a fish, causing hiccups.

2. Eat too much

Some people eat too fast, or eat and talk at the same time, this will make the gas in the stomach become more, but the stomach has no way to discharge them. Once the gas returns, there will be hiccups. The more gas gets into the stomach, the longer the burp takes. So, don't eat too fast, don't eat too much, let alone talk.

3. Food stimulation

This part of hiccups is often caused by dyspepsia, so stimulating food will stimulate the stomach and cause hiccups. The first thing to avoid burping is to avoid or reduce the amount of irritant food (spicy, cold, etc.), and the second is to properly regulate the gastrointestinal tract.

4. Stomach diseases

Belching can also occur when the stomach is sick. Once the stomach gets sick, it means that the ability of digestion and absorption becomes weak. At this time, when you are full, you will burp. However, if you eat spicy and irritant food, in addition to burping, there will be pain and other abnormal conditions. People who have this situation are mostly ill. It's better to go to the hospital immediately for examination and diagnosis to avoid missing the best time for treatment.

5. Cold weather

The stimulation of cold wind for a long time leads to contraction of human diaphragm, and then causes hiccups. This kind of burping has no harm to the body. As long as we keep warm and cold in time, the burping phenomenon will disappear.

Generally speaking, burping is normal. We don't need to worry too much. We will get better after a while. However, if you have hiccups for a long time, accompanied by pain, high fever and other abnormal symptoms, you should be alert. It is likely that you have some disease, you must go to the hospital immediately for examination and treatment, so as to avoid life danger.
