Primary Systems:

Nervous System:

• Brainstem - vomiting center
• Hypothalamus - stress response
• Limbic system - emotional processing
• Trigeminal nucleus - migraine connection

Gastrointestinal System:

• Stomach - site of vomiting
• Esophagus - affected by reflux
• Small intestine - affected by motility changes

Endocrine System:

• HPA axis - stress hormone regulation
• Adrenal glands - cortisol production
• Thyroid - metabolic regulation

Related Structures:

• Autonomic nervous system
• Vagus nerve (X)
• Sympathetic nervous system

The pathophysiology of CVS involves:

1. Trigger Activation - Stress, infection, certain foods activate the system
2. Brain-Gut Activation - Hypothalamic activation triggers vomiting center
3. Autonomic Dysfunction - Altered sympathetic/parasympathetic balance
4. Gastric Dysmotility - Stomach slows or stops emptying
5. Vomiting Cascade - Repetitive vomiting ensues
6. Recovery - Gradual return to baseline

This explains why CVS responds to migraine medications and stress management.

By Trigger Pattern:

1. Classic Cyclic Vomiting

   • No obvious trigger identified
   • Classic cyclical pattern
   • Often migraine-associated

2. Stress-Induced CVS

   • Emotional or physical stress triggers episodes
   • Predictability varies
   • Common in high-achievers

3. Food-Triggered CVS

   • Specific foods precipitate episodes
   • Often chocolate, cheese, or preservatives
   • May be related to histamine

4. Menstrual-Associated CVS

   • Episodes linked to menstrual cycle
   • Hormonal fluctuations trigger
   • More common in adult women

5. Infectious-Triggered CVS

   • Episodes follow minor illnesses
   • Often URI or GI infection
   • May have post-viral component

Migraine Biology: CVS is now understood as a migraine variant. The same mechanisms that cause migraine headaches can manifest as cyclical vomiting in some individuals. This includes cortical spreading depression, trigeminal nerve activation, and neuroinflammatory cascades.

Autonomic Dysfunction: Many CVS patients have underlying autonomic nervous system abnormalities. This affects heart rate, blood pressure, digestion, and stress response. The vagus nerve, which controls nausea and vomiting, appears particularly involved.

Mitochondrial Dysfunction: Some research suggests impaired mitochondrial function in CVS patients. This affects cellular energy production and may explain why episodes can be triggered by metabolic stressors like fasting, illness, or exhaustion.

Common Triggers:

• Emotional stress (excitement, anxiety, school/work pressure)
• Physical stress (illness, lack of sleep, exhaustion)
• Certain foods (chocolate, cheese, MSG, nitrates)
• Menstrual periods
• Fasting or skipping meals
• Dehydration
• Motion sickness susceptibility
• Weather changes

At Healers Clinic, we investigate CVS through our "Cure from the Core" philosophy:

1. Migraine Susceptibility - Is there a migraine component?
2. Trigger Pattern - What specifically triggers episodes?
3. Autonomic Function - Is there dysautonomia?
4. Mitochondrial Health - Are there metabolic factors?
5. Stress Response - How does the body handle stress?
6. Hormonal Factors - Are there hormonal triggers?
7. Gut-Brain Axis - Is there dysfunction in this communication pathway?
