26M and really anxious something serious is being missed.
For months I’ve had bad reflux/gastritis symptoms, throat tightness, poor appetite, and weight loss (180 down to 166). I barely feel hungry and sometimes go long stretches without eating because my stomach/throat feels off.
Recently I’ve also had:
- heart rate around 130 (ER said sinus tach, normal EKG)
- weakness/shaking
- itching improved with Zyrtec
- occasional hand redness/flushing
- on/off throat tightness
Labs:
- CO2: 19 (low)
- Anion gap: 18 (slightly high)
- BUN: <3–4 (low)
- Total protein: 8.6 (slightly high)
- Liver/kidney labs normal
- Pulse ox 99%
- VBG pH ~7.33, bicarbonate normal
I keep worrying about sepsis, lactic acidosis, liver failure, blood cancer, or MCAS, but doctors don’t seem too concerned.
Does this sound more like dehydration/fasting + reflux/anxiety, or should I push harder for GI workup or MCAS testing?
