Causes

There are many theories about the causes of HG, but none have been confirmed. HG is a complex disease that is likely caused by many factors. Some of these include:

Treatment

Treating HG symptoms early in pregnancy can make you less sick in the long run and can decrease recovery time. Because HG is caused by many factors that vary among women, it is difficult to find a treatment that works for everyone. Talk with your doctor about the best treatment plan for you. Treatment options include the following:

Diet

Try to eat frequent, small meals, bland or dry foods, high-protein choices.

Anti-nausea Medications

Reducing nausea, and thus allowing eating and drinking, will hasten recovery. Due to the risk of stating that a drug is safe for use during pregnancy, very few pharmaceutical manufacturers will say that their drugs are intended for a pregnancy condition like HG. However, doctors often recommend that women with HG take certain anti-nausea medications, balancing the potential benefits and risks. Talk to your doctor about the right medications for you.
A common and safe remedy is to take supplemental vitamin B6 (pyridoxine). The American Congress of Obstetricians and Gynecologists recommends that first-line treatment of nausea and vomiting of pregnancy should start with pyridoxine with or without doxylamine. Pyridoxine has been found to be effective in significantly reducing severe vomiting.

IV Hydration and Anti-nausea Medications

In urgent visit situations, HG can be managed by IV fluids and vitamins. This can sometimes be done without hospitalization. Very rarely, some people require IV fluids throughout the entire pregnancy.

Nutrition by Vein

If you are unable to tolerate food by mouth, you may need to receive nutrition by vein. This is called parenteral nutrition. A special kind of catheter is placed in a large vein and liquid nutrition is given. This can sometimes be done without hospitalization.

Alternative Therapy

Acupressure may help to reduce nausea. Acupressure is when pressure is applied to acupuncture points.

Termination of Pregnancy

In extreme cases, induced abortion may be considered.
