Hyperemesis gravidarum is extreme, persistent nausea and vomiting during pregnancy. It can lead to dehydration, weight loss, and electrolyte imbalances. Morning sickness is mild nausea and vomiting that occurs in early pregnancy. Hyperemesis gravidarum tends to occur in the first trimester of pregnancy and lasts significantly longer than morning sickness. While most women will experience near-complete relief of morning sickness symptoms near the beginning of their second trimester, some sufferers of HG will experience severe symptoms until they give birth to their baby, and sometimes even after giving birth. 
Hyperemesis gravidarum is a pregnancy complication that is characterized by severe nausea, vomiting, weight loss, and possibly dehydration. Signs and symptoms may also include vomiting many times a day and feeling faint. Hyperemesis gravidarum is considered more severe than morning sickness. Often symptoms get better after the 20th week of pregnancy but may last the entire pregnancy duration. The exact causes of hyperemesis gravidarum are unknown. Risk factors include the first pregnancy, multiple pregnancy, obesity, prior or family history of HG, trophoblastic disorder, and a history of eating disorders.
Diagnosis is usually made based on the observed signs and symptoms. HG has been technically defined as more than three episodes of vomiting per day such that weight loss of 5% or three kilograms has occurred and ketones are present in the urine. Other potential causes of the symptoms should be excluded including urinary tract infection and high thyroid levels.
Signs and symptoms of hyperemesis Gravidarum:
*When vomiting is severe it may result in the following:
*Loss of 5% or more of pre-pregnancy body weight,
*Dehydration, causing ketosis,  and constipation
*Nutritional disorders such as vitamin B1 (thiamine) deficiency, vitamin B6
 deficiency or vitamin B12 deficiency
*Metabolic imbalances such as metabolic ketoacidosis or thyrotoxicosis
*Physical and emotional stress of pregnancy on the body
*Difficulty with activities of daily living

Symptoms can be aggravated by hunger, fatigue, prenatal vitamins (especially those containing iron), and diet. Many people with HG are extremely sensitive to odors in their environment; certain smells may exacerbate symptoms. Excessive salivation, also known as sialorrhea gravidarum, is another symptom experienced by some women.
