Anatomy & Body Systems
Affected Body Systems
Primary Systems:
Hormonal System:
- Placenta - produces hCG and other hormones
- Thyroid - can be affected by hCG
- Adrenal glands - stress hormone regulation
- Ovaries - produce hormones
Gastrointestinal System:
- Stomach - site of nausea and vomiting
- Esophagus - affected by reflux
- Liver - metabolic changes
- Pancreas - enzyme production
Central Nervous System:
- Vomiting center in brainstem
- Chemoreceptor trigger zone
- Hypothalamus - hormone regulation
Other Systems:
- Cardiovascular - fluid balance
- Renal - electrolyte handling
- Musculoskeletal - weakness from dehydration
The exact cause of HG is multifactorial:
- Rising hCG levels stimulate vomiting center
- Hormonal changes affect gut motility
- Altered smell and taste sensitivity
- Delayed stomach emptying
- Autonomic nervous system changes
- Psychological factors may amplify symptoms

Causes & Root Factors
Hormonal Factors: Elevated human chorionic gonadotropin (hCG) is strongly associated with HG. Levels peak around weeks 8-11 when symptoms are often worst. This explains why HG is more common in molar pregnancies (very high hCG) and multiple pregnancies (higher hCG).
Genetic Predisposition: Women with family history of HG are more likely to experience it themselves. Studies suggest hereditary components, possibly related to hormone metabolism or vomiting center sensitivity.
Previous History: Women who experienced HG in a previous pregnancy are much more likely to have it again, often more severely.
Gastrointestinal:
- Altered gut motility
- Delayed stomach emptying
- Increased acid production
- Heightened smell/taste sensitivity
Neurological:
- Increased sensitivity of vomiting center
- Autonomic dysfunction
- Migraine association
Psychological:
- While not "all in the head," psychological factors can amplify symptoms
- Stress may worsen symptoms
- Anxiety about the condition
At Healers Clinic, we view HG through our "Cure from the Core" philosophy:
- Hormonal Assessment - How are pregnancy hormones affecting function?
- Nutritional Status - Is there underlying deficiency?
- Digestive Function - Is gut motility affected?
- Stress Load - How is stress impacting symptoms?
- Constitutional Factors - What's the mother's overall health picture?
