Now I have enough to give a thorough answer. Let me compile the full response with differential diagnoses and treatment:
Clinical Scenario: 24-year-old Female with Headache and Vomiting After Food
This presentation is broad enough to encompass several diagnoses. The age (young female), the combination of headache + vomiting, and the temporal link to food are the key clinical anchors.
Differential Diagnoses
1. MIGRAINE (Most Likely Diagnosis)
This is the top diagnosis to consider. Migraine is far more common in women (3:1 female-to-male ratio) and peaks in the 20-30 year age group. Food is one of the most well-known triggers (tyramine in aged cheese, chocolate, caffeine withdrawal, alcohol, processed meats). Vomiting is a core associated symptom.
ICHD-3 Diagnostic Criteria for Migraine Without Aura (at least 5 attacks fulfilling):
- Duration 4-72 hours
- At least 2 of: unilateral location, pulsating quality, moderate-severe intensity, aggravation by routine physical activity
- At least 1 of: nausea/vomiting OR photophobia + phonophobia
- Not better explained by another disorder
(Kaplan & Sadock's Comprehensive Textbook of Psychiatry; Tintinalli's Emergency Medicine)
Key features supporting migraine here: young woman, headache + vomiting, food as a trigger.
2. IDIOPATHIC INTRACRANIAL HYPERTENSION (Pseudotumor Cerebri)
Important to consider in young women, especially if obese. Presents with headache (84% of cases), nausea/vomiting, transient visual obscurations, pulsatile tinnitus, and back pain. The headache is typically diffuse and worsened by Valsalva. Papilledema is a hallmark finding on fundoscopy.
- Diagnostic criteria: elevated opening pressure on LP (>25 cm H2O) + normal CSF composition + normal imaging
- "The incidence is 19.3 per 100,000 obese women between the ages of 20 and 44 years." (Tintinalli's Emergency Medicine)
3. FOOD POISONING / GASTROENTERITIS
If the headache + vomiting onset is within 1-6 hours of eating, consider preformed bacterial toxin (e.g., Staphylococcus aureus, B. cereus). This typically presents with abrupt nausea, vomiting, and cramping - headache may occur as a secondary feature from dehydration or the systemic response. Diarrhea is often but not always present. (ROSEN's Emergency Medicine)
4. OTHER SECONDARY HEADACHES TO RULE OUT
| Condition | Red Flags Suggesting This |
|---|---|
| Meningitis/Encephalitis | Fever, neck stiffness, altered sensorium |
| Subarachnoid Hemorrhage | "Thunderclap" worst-ever headache, sudden onset |
| Intracranial Hypertension (mass lesion) | Progressive headache, worse in morning, papilledema |
| Hypertensive crisis | BP >180/120, blurry vision |
Treatment of Choice
For Migraine (Most Likely)
Step-wise approach:
Acute/Abortive Treatment:
| Drug | Dose | Notes |
|---|---|---|
| NSAIDs (1st line - mild attacks) | Ibuprofen 400-600 mg PO or Ketorolac 10-30 mg IV/IM | First-line for mild-moderate migraine |
| Triptans (1st line - moderate-severe) | Sumatriptan 50-100 mg PO / 6 mg SC / 20 mg nasal; Zolmitriptan 2.5-5 mg | 5-HT1B/1D agonists; abort headache in ~70% of patients; give early |
| Antiemetics | Prochlorperazine 5-10 mg IV/PR; Metoclopramide | Both controls vomiting and has direct antiheadache effect |
| Ergot alkaloids | Dihydroergotamine (DHE) nasal/IV | For severe/refractory attacks |
| CGRP antagonists (gepants) | Rimegepant, Ubrogepant | Newer option; useful when triptans are contraindicated |
(Adams and Victor's Principles of Neurology, 12th Ed.; Lippincott Illustrated Reviews Pharmacology; Tintinalli's Emergency Medicine)
Triptans are contraindicated in patients with coronary artery disease, uncontrolled hypertension, hemiplegic migraine, or history of stroke.
Preventive Treatment (if attacks ≥4/month or significantly debilitating):
- Beta-blockers: Propranolol 40-240 mg/day
- Topiramate 25-100 mg/day
- Amitriptyline 10-75 mg/night
- CGRP monoclonal antibodies: Erenumab, Fremanezumab (monthly injection)
For IIH (if suspected):
- Acetazolamide 250-500 mg twice daily (up to 4 g/day)
- Weight loss in obese patients
- LP with CSF drainage for acute relief
- Surgical: optic nerve sheath fenestration or CSF shunting for failing vision
For Food Poisoning:
- Supportive: oral/IV rehydration
- Antiemetics (ondansetron, metoclopramide)
- Antibiotics only if systemic illness or specific pathogens identified
Clinical Approach Summary
- Full history: headache character (unilateral? throbbing?), duration, aura, prior episodes, exact timing after food, associated fever/neck stiffness, visual symptoms, BMI
- Examination: BP, fundoscopy (papilledema?), meningeal signs, neurological exam
- If red flags present: CT head (rule out bleed/mass), LP (rule out SAH/meningitis)
- If classic migraine with no red flags: treat empirically with NSAIDs + antiemetic; add triptan if severe
- Lifestyle counseling: identify and avoid food triggers (tyramine, caffeine, MSG, alcohol), maintain regular sleep/meals/hydration
