Bile is yellowish in color and vomiting a lot of it is not a cause of concern but it should not be ignored. Medical checkup is required to ensure that there is no underlying condition.
Bile is produced in the liver to help in food digestion. It also helps in eliminating worn out blood cells. Throwing up bile can be caused by food allergies, surgery, gastroenteritis, alcohol intolerance, intestinal blockage and food poisoning, as stated by MDhealth . It can be treated by limiting a diet, keeping the body hydrated and taking bile acid sequestrants. A person is advised to observe what happens to their body prior to vomiting to allow easy diagnosis of the condition.
