Extreme Pregnancy Nausea

Biological, psychological and sociocultural factors may all contribute to the chance that a woman's morning illness will create in to HG. Females carrying female fetuses and multiple fetuses are known to be at greater risk. Occurrence of HG has also been associated with hyperthyroid disorders, psychiatric illnesses, earlier molar pregnancy, gastrointestinal disorders, preexisting diabetes, and asthma. Risk of HG is higher for females in their first pregnancy, those who experienced NVP in earlier pregnancies, and females who had nausea due to oral contraceptives.

While the exact cause of hyperemesis gravidarum remains unknown, some theories have emerged:

Hormones: Pregnancy triggers the creation of a new hormone called hCG, which has a stimulant effect on the thyroid. high levels of hCG apparently may cause temporary hyperthyroidism. The severity of nausea appears to be related to the degree of thyroid stimulation. If the stimulation is strong , hyperthyroidism can be clinically identified, but in milder cases it is "transient" and no clinical signs may be observable. In transient hyperthyroidism, the thyroid usually returns to normal by itself by the middle of the pregnancy without requiring antithyroid treatment.

Gastrointestinal causes: Another theory suggests that HG is more likely to occur in females whose gastrointestinal systems are sensitive. Lots of of the physical changes associated with pregnancy are also known to disrupt normal gastric function, including increased levels of estrogen or progesterone, thyroid disorders, disturbances of the sympathetic nervous method, blood pressure fluctuations and water retention.

Bacterial infection: Infection with the Helicobacter pylori bacteria in the stomach can presumably multiply the effect of NVP sufficiently to cause peptic ulcers and lead to HG.

Liver disorders:  half of females who suffer from HG also show signs of liver malfunction, which has led to speculation that preexisting liver impairment could be a contributing cause. It is fascinating that untested preventive treatment for HG is milk thistle extract prior to pregnancy, which is claimed to have a liver cleansing effect.

Inner ear and olfactory sensitivity: The similarity of NVP and HG to motion illness suggests that pregnancy illness may in some cases even be caused by vestibular disorders. Inner ear issues usually are linked to signs like dizziness, vertigo, nausea, and fatigue. It is also common for pregnant females to become hypersensitive to food smells, which frequently trigger episodes of nausea. Females with higher susceptibility to these issues prior to pregnancy could be a greater risk of HG.
