I have bulimia and i noticed pink streaks in my vomit. is it blood and is it dangerous?

Yes and yes: Vomiting can cause tears in the esophagus and more complications, as if bulimia alone was not bad enough. Please seek counseling for the condition. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex. Get HPV vaccine.
