Vomiting is one of the body's normal responses to the presence of foreign substances or microorganisms in the body, however it can also be a sign of gastric diseases, and should therefore be investigated and treated as soon as possible.
The color of the vomit can also indicate the person's health status, which may be yellow or green in case of colds or even fasting, or black when there are serious digestive diseases that lead to bleeding in organs of the digestive system and result in the release of blood through the mouth.
The color of the vomit can inform the doctor about the person's health, thus being able to start treatment and prevent complications.
1. Yellow or green vomiting
Yellow or green vomiting mainly indicates the release of bile that is in the stomach, often due to fasting, an empty stomach or intestinal obstruction, for example. Bile is a substance produced by the liver and stored in the gallbladder and its function is to promote the digestion of fats and facilitate the absorption of nutrients in the intestine.
Thus, when the stomach is empty or when the person has a condition that leads to intestinal obstruction, and the person vomits the entire contents of the stomach, and begins to release bile through vomiting and the more bile released, the more greenish the vomit is.. In addition to the release of bile, green or yellow vomiting can be caused by:
- Presence of phlegm, being more common in children with colds or flu; Consumption of yellow or green food or drinks; Release of pus due to an infection; Poisoning.
Yellow or green vomiting does not normally represent serious situations, and may be just an indication that the stomach is empty, for example. However, when accompanied by other symptoms or when it is very frequent it can mean serious health problems, it is important to go to the doctor.
