Based on what you’ve described, this pattern strongly suggests a functional gastrointestinal cause, most commonly acid reflux / gastritis / GERD, rather than a heart,
thyroid, or
sugar-related problem (which you’ve already ruled out with tests).
Key points supporting this:
• Discomfort in upper abdomen / below the breastbone (epigastric area)
• Symptoms worsen at night and disturb sleep
• Occasional back pain (reflux pain can radiate)
• Temporary relief when you took acidity/gastric medication
• Anxiety around sleep can amplify symptoms, even if it’s not the root cause
Hormonal changes around periods can trigger or worsen reflux, but once the stomach lining is irritated, symptoms can persist even after periods end.
Next Steps
What you should do now:
1. Medication (short-term, doctor-guided)
• A PPI (like pantoprazole / esomeprazole) once daily before breakfast
• Add an antacid or alginate (after dinner or before bed)
• If bloating or heaviness is prominent → a prokinetic may help
2. Night-time precautions (very important)
• Eat dinner at least 3 hours before sleep
• Avoid lying flat immediately after meals
• Elevate head end of bed by 4–6 inches
• Avoid tea, coffee, chocolate, spicy/fried food in the evening
3. If symptoms persist beyond 2–3 weeks
• Get evaluated for H. pylori
• Consider upper GI evaluation if pain, weight loss, vomiting, or anemia appear
Health Tips
• This condition is very common and treatable, but needs consistency, not just 1–2 days of medicines
• Poor sleep itself worsens gastric symptoms → it becomes a vicious cycle
• Avoid Googling cardiac causes once ECG is normal — it increases anxiety and worsens reflux
• Gentle walking after dinner helps digestion significantly
• Warm fluids (not very hot) before bed may reduce discomfort
