Upset stomach, indigestion, dyspepsia-no matter what you call it, it's not fun. Indigestion may be caused by digestive conditions such as ulcers or GERD or certain medications. More commonly, indigestion is caused by diet and lifestyle patterns such as :

Overeating

Eating too fast

Eating too many high-fat foods

Eating in stressful environments

Smoking

Drinking too much alcohol

Stress

Often, the best way to address indigestion is by simply avoiding the foods or situations which seem to cause it. Here are some diet and lifestyle tips to help avoid indigestion:

Avoid late-night eating

Avoid exercising on a full stomach

Try drinking fluids after meals, rather than during

Eat slowly

Stop smoking

Because some people have indigestion not caused by diet and lifestyle (functional or nonulcer dyspepsia), it is important to consult your doctor for proper treatment.
