What Does The Colour of Your Vomit Mean?

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, may be yellow or green in the case of flu or even fasting, or black when there are serious digestive diseases that lead to bleeding in organs of the digestive system and results in the release of blood through the mouth.

The color of the vomiting can inform the doctor how the person's health is, so they can start treatment and prevent complications.

1. Yellow or green vomit

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 has the function of promoting the digestion of fats and facilitating the absorption of nutrients in the intestine.

Thus, when the stomach is empty or when the person has some 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. In addition to the release of bile, green or yellow vomiting can be caused by:

  • Presence of phlegm, being more common in flu or cold children;
  • Consumption of yellow or green food or drinks ;
  • Pus release due to infection;
  • Poisoning.

Yellow or green vomiting does not normally represent serious situations, and may only be indicative that the stomach is empty, for example. However, when accompanied by other symptoms or when it is very common it can mean serious health problems, it is important to go to the doctor.

What to do: In addition to consulting the gastroenterologist or general practitioner when vomiting is frequent or associated with other symptoms, it is also important to drink plenty of fluids, such as water or coconut water, to prevent dehydration and worsening of symptoms, in addition to maintaining a balanced and healthy diet.

2. Black vomit

Black vomiting is usually indicative of digestive bleeding, consisting mainly of undigested blood and is called hematemesis. Usually black blood is associated with other symptoms, such as dizziness, cold sweat and bloody stools.

Digestive hemorrhage corresponds to bleeding somewhere in the digestive system, which can be classified as high or low according to the affected organ. This bleeding can be caused by the presence of stomach or bowel ulcers, Crohn's disease and cancer of the intestine or stomach, for example.

What to do: In the case of black vomiting, it is important to go to the doctor as soon as possible so that tests can be performed and the cause can be identified by starting treatment, which can be done through blood transfusion, use of medications or even surgery, depending on the cause. In addition, it is also recommended to drink plenty of fluids to prevent dehydration.
