Drinking alcohol and vomiting brown liquid may be caused by dietary factors, gastrointestinal bleeding, gastric ulcers and other reasons.
1. Dietary factors: If the patient eats brown food, which is not fully digested in the stomach, the vomit may appear brown.
2. Gastrointestinal bleeding: if the patient suffers from gastrointestinal bleeding, the blood will stay in the stomach for a period of time and may form brown substances, so the vomit may appear brown liquid.
3. Gastric ulcer: If the patient suffers from gastric ulcer, the ulcer may bleed after being stimulated when the patient vomits, so the patient may vomit brown liquid.
It is recommended that the patient should go to the hospital when he is not feeling well, so as not to delay his condition.
