Morning Sickness Symptoms & Diagnosis

Symptoms

The following list of symptoms are general and may be caused by other, less serious health conditions. However, if you experience any one of them, call your physician to discuss your condition. Symptoms may include:

• Severe and persistent vomiting, beginning 4 to 6 weeks after conception, peaking between 9 to 13 weeks, and usually improving and ending between 14 to 20 weeks
• Progressive weight loss of greater than 5% of original, pre-pregnancy body weight
• Dehydration, which may show the following signs:
  • Ketones in urine
  • Increased hematocrit (% of red blood cells in blood)
  • Increased pulse rate
  • Decreased blood pressure
• Rapid heartbeat ( tachycardia )
• Excessive salivation (ptyalism)
• Distinctive breath odor (ketonic odor)

Diagnosis

Your doctor will ask about your symptoms and medical history, and perform a physical exam.

Tests may include the following:

• Weight measurement—to determine if you have lost weight
• Blood electrolytes—to identify disturbances in salts and other minerals in the blood due to extreme vomiting
• Ketones—to determine if you are dehydrated
• Overall condition—ability to perform daily activities; psychological state of mind
