Most stomach aches can be treated at home. During the first 24 to 36 hours, the best treatment is a diet
of clear liquids in frequent, small amounts. Drink enough fluids to keep your urine a pale yellow or clear
color. If you vomit, start with sips of water or sucking on ice chips.
People should seek immediate medical attention if they experience stomach pain alongside:
severe or sudden pain
sweating
a tender or painful stomach
vomiting blood or if vomit looks like ground coffee
sticky, bloody, or black feces
difficulty passing urine, feces, or gas
difficulty breathing
chest pain
weight loss or loss of appetite
jaundice
