It is important to be careful when making yourself throw up because the process can be uncomfortable or painful. If you scratch or burn the throat while making yourself throw up you can do permanent damage to the body.
Warning: There are some circumstances in which forcing yourself to vomit is not an appropriate course of action. If you are concerned that you have injected something poisonous, contact poison control to determine the best course of action before you try self-care like making yourself throw up. Do not try to induce vomiting for someone who ingested something inappropriate and is unconscious as this can cause them to choke. Self-induced vomiting should also be avoided as a weight loss alternative. Frequent vomiting can rob the body of vital nutrients and cause erosion of the teeth and esophagus from frequent contact with stomach acid.
Beforehand, plan where you will throw up so that you can avoid making a mess. Throwing up in the bathroom over the toilet or using a plastic bag are common choices.
Sit in a comfortable position that puts minimal stress on your abdomen so that your muscles do not have to overwork themselves to expel the contents of your stomach. In between cycles of vomiting, try to breath at a normal rate to avoid overexerting your body. If possible, rinse your mouth out with water in between bouts of sickness to avoid leaving stomach acid or food fragments remaining in the throat for long periods of time.
Now that you know how to make yourself throw up, there's also precaution to be taken.
After you have induced vomiting it is important to help replenish what you have lost. Take a few moments to sit, relax and allow the nausea to pass. Once you are sure that you will not throw up again, drink a glass of cold water to ensure that you will not become dehydrated. You should also brush your teeth and tongue to remove any lingering stomach acid from your mouth which could cause damage to your teeth. Do not try to eat until you are feeling up to it again. When you are hungry, start out with bland foods like rice, crackers or broth to avoid over-stimulating your system.
