When appearing shortly after a meal, nausea or vomiting may be caused by food poisoning, gastritis (inflammation of the stomach lining), an ulcer, or bulimia. Nausea or vomiting one to eight hours after a meal may also indicate food poisoning.
What is bulimia? Bulimia is eating an unusual amount of food at once (called bingeing), and then getting rid of it. This includes throwing up or using laxatives to remove the food from the body (called purging).
Check if you have gastroparesis
Symptoms of gastroparesis start after eating and may include: feeling full sooner than usual – you may be unable to finish meals. feeling sick and being sick.
It's normal to not like certain foods. Food aversion causes you to reject a specific food because your brain tells your body that it's inedible. It also causes your body to react negatively by feeling nauseous or gagging, at the sight, scent or taste of the food.
What To Do if You're Hungry But Don't Want to Eat. If you know your body is hungry but you don't want to eat, there are a few simple tips you can apply at home. These include focusing on smaller, more frequent meals and choosing bland, low-fiber foods.
With some conditions -- or their treatments -- you can't keep food down because you get nausea, vomiting, or diarrhea. Try this: Stick to bland foods like crackers, toast, potatoes, noodles, and rice. Try eating very small meals, 6-8 a day.
While a common cause is a gastrointestinal virus, without a diagnosis from a health care provider, it is possible that your constant upheaval could be caused by multiple things: food poisoning, a migraine, motion sickness, recent exposure to general anesthesia, rotavirus, and alcohol use, to name a few.
Speak to your GP if:
you've been vomiting repeatedly for more than a day or two. you're unable to keep down any fluids because you're vomiting repeatedly. you have signs of severe dehydration, such as confusion, a rapid heartbeat, sunken eyes and passing little or no urine.
Do not eat or drink anything for several hours after vomiting. Sip small amounts of water or suck ice chips every 15 minutes for 3-4 hours. Next, sip clear liquids every 15 minutes for 3-4 hours. Examples include water, sports drinks, flat soda, clear broth, gelatin, flavored ice, popsicles or apple juice.
Gastroparesis means paralysis of the stomach. It's a functional disorder affecting your stomach nerves and muscles. It makes your stomach muscle contractions weaker and slower than they need to be to digest your food and pass it on to your intestines.
Dumping syndrome is a group of symptoms, such as diarrhea, nausea, and feeling light-headed or tired after a meal, that are caused by rapid gastric emptying. Rapid gastric emptying is a condition in which food moves too quickly from your stomach to your duodenum.
Allow yourself to rest. Resting propped up in a seated position with the head elevated at least twelve inches above the feet is ideal. Remain in this seated rested position for a minimum of an hour, or until you are no longer experiencing nausea. Do not lie down all the way.
Call Your Doctor If:

Contrary to how yucky it may feel, it's not great to brush your teeth right after vomiting. It's best to swish water around your mouth with a touch of baking soda after vomiting. We recommend waiting at least 30 minutes before brushing. Brushing immediately after rubs the stomach acid on teeth.
Vomiting episodes may be triggered by: emotional stress, such as excitement, anxiety or panic attacks. physical stress, such as an infection, exhaustion, or lack of sleep. some foods and drinks, such as chocolate, cheese, and things that contain caffeine, alcohol or MSG (monosodium glutamate)
