(HealthDay) -- Though it's common during pregnancy, experts don't know what causes morning sickness. Most cases aren't serious and go away on their own.
The Delray (Fla.) Medical Center says over-the-counter remedies such as antacids and even seasickness remedies usually ease the problem. The center says studies have found that women who are happy about being pregnant have fewer morning-sickness problems than those who didn't plan on having a child.
Before trying any medicines, the medical center says to be sure to consult your doctor.
