The causes of heartburn are very common, leading many people to have sour stomach and other symptoms of acid indigestion. Changes in diet and lifestyle and other heartburn prevention measures may reduce or stop your heartburn.

If you do need heartburn treatment, there are a wide variety of over-the-counter remedies available. Or, you may need to seek prescription heartburn relief or other, stronger heartburn treatment.

Another common digestive problem is excess gas. That the bloating, pressure, and discomfort of gas are so common should not be surprising. The causes of gas can include such commonplace activities such as air swallowing, some everyday foods and beverages, poor muscle tone, smoking, chewing gum, and even wearing tight-fitting clothes. At times, medicine may be necessary to help expel the excess gas that gets trapped in your stomach and intestines.

When everything is working correctly, cells lining the small intestine absorb nutrients and water as food and liquid move through. You get diarrhea when irritated cells keep the nutrients and water from being absorbed or sometimes may cause your intestines to move things through too fast.

If you get an upset stomach after eating dairy foods, you may be lactose intolerant. An estimated one-in-five Americans are lactose intolerant. The trouble starts if your body lacks the ability to digest lactose, the sugar in dairy foods such as milk, ice cream, yogurt, and cheese. Undigested lactose can cause excess gas, bloating, diarrhea, and other problems.

Fast-paced, adult lifestyles may aggravate heartburn, excess gas, and other digestive health problems. That doesn't mean infants and children don't get these symptoms, too.

• Gas in Infants
  As anyone who ever burped a newborn knows, gas is very common in babies, leading to crankiness and crying. Almost half of all babies suffer from it in their first two months. Infants with gas may try to relieve the symptoms by curling up or pulling up their legs.
  
  Ask your pediatrician about treating your infant's gas with MYLICON® Drops.

• Stomach Upset
  "Tummy aches" could be the most common complaint parents hear from their kids. That stomach upset often comes from acid indigestion or sour stomach caused by excess stomach acid. Unfortunately, kids are subject to many of the same causes of heartburn as adults, including overeating, food sensitivities, viral infections, or other unknown factors.
  
  While parents used to face limited options, Children's MYLANTA® finally provides a safe, effective way to treat your child's upset stomach.
