Food coming back up and chest symptoms could be acid reflux, aka GERD.
Google GERD and you'll get lots of info on it!!! There are also lots of natural remedies other than the meds prescribed by doctors. Check out Drweil.com. Type GERD into the search box. You'll get lots of info.
The twisting feeling may be acid churning in your stomach. Maybe your body produces too much stomach acid???
There are many things you can do on your own:
Control your weight. Being overweight is one of the strongest risk factors for heartburn. Excess pounds put pressure on your abdomen, pushing up your stomach and causing acid to back up into your esophagus.
Eat smaller meals. This reduces pressure on the lower esophageal sphincter, helping to prevent the valve from opening and acid from washing back into your esophagus.
Loosen your belt. Clothes that fit tightly around your waist put pressure on your abdomen and the lower esophageal sphincter.
Eliminate heartburn triggers. Everyone has specific triggers. Common triggers such as fatty or fried foods, alcohol, chocolate, peppermint, garlic, onion, tomatoes, caffeine and nicotine may make heartburn worse.
Avoid stooping or bending. Tying your shoes is OK. Bending over for longer periods to weed your garden isn't, especially soon after eating.
Don't lie down soon after a meal. Wait at least two to three hours after eating before going to bed, and don't lie down right after eating.
Raise the head of your bed. An elevation of about six to nine inches puts gravity to work for you. You can do this by placing wooden or cement blocks under the feet of your bed at the head end. If it's not possible to elevate your bed, you can insert a foam wedge between your mattress and box spring to elevate your body from the waist up. Wedges are available at drugstores and medical supply stores. Raising your head only by using pillows is not a good alternative. If you need to raise the head of your bed most nights, talk to your doctor because it may indicate GERD and require stronger medication and evaluation.
Don't smoke. Smoking may increase stomach acid. The swallowing of air during smoking may also aggravate belching and acid reflux. In addition, smoking and alcohol increase your risk of esophageal cancer.
