During the first three months of gestation, about 80% of pregnant women suffer from nausea, morning in many cases, sometimes more persistent during the day.
Overall this is an annoying noise but not disturbing: even when symptoms are intense not affect the overall health of the mother and child. However, in a small percentage of cases (0,5-2% approximately) the phenomenon can be disabling enough to be considered a real disease, known as hyperemesis gravidarum (IG), which requires early intervention to prevent the loss of significant quantities of mineral salts and an overall state of undernourishment.
The causes
In general, the GI appears between the second and third months of pregnancy and disappears after the fourth. Epidemiological studies have revealed that suffer are more frequently young women with a previous history of GI, diabetes, depression, thyroid disorder and gastrointestinal disease are considered risk factors. Numerous studies have also shown a correlation between the appearance of IG and a female fetus. Dell'iperemesi The etiology has not yet been fully elucidated, but is believed to be the result of complex interactions between biological, psychological and socio-cultural. Certainly, they must be detectable in the vegetative nervous system disorders due to elevated serum human chorionic gonadotropin (hCG) and estrogen.
Symptoms
To establish a diagnosis correct any other possible cause of nausea and vomiting (hepatitis, pancreatitis, obstruction of the gastrointestinal tract, disorders of the thyroid, ulcers) should be excluded, especially when the symptoms begin after the IG first trimester of pregnancy. There is, in fact, a specific examination and diagnosis for hyperemesis gravidarum. The GI is characterized by frequent and repeated vomiting throughout the day, resulting in fatigue, progressive dehydration, weight loss, increased heart rate. In some cases blood tests reveal an increase of ketones (substances produced by the body in case of shortage of sugar) in the blood.
