Hi everyone,

I'm trying to make sense of two specific reactions that derailed my whole system. Maybe someone here recognizes the pattern.

Background (short): 28 F, BMI 17.5, documented severe gut dysbiosis after antibiotics in 2024 (Akkermansia 0 %, all neuroactive species 0 %), elevated plasma histamine (tryptase normal, IgE neg). Low BP since adolescence. After 6 months of rebuilding with baobab + L-glutamine + probiotics I was almost stable — then these two events happened.

Event 1 – Supplement cocktail on empty stomach

Taken in the morning on an empty stomach:

• L-glutamine
• Vitamin C
• Baobab powder
• Probiotics

Within hours: weakness, numbness, BP drop, deep exhaustion → ER.

Bloodwork: hyponatremia (Na 132), metabolic acidosis (TCO₂ 19), strong stress leukocytosis with lymphopenia + eosinopenia. No infection.

Event 2 – NAC at a normal dose

A single substance, normal daily dose (~600 mg): NAC (N-acetylcysteine).

Reaction: near-syncope, drastic energy crash, bedridden. Recovery over weeks insufficient, energy never came back.

What both events have in common:

• Systemic reaction (not local): BP, energy, CNS
• Massively disproportionate to substance amount
• Long after-effects (days to weeks)
• Substrate-unspecific – different pharmacological profiles, similar reaction pattern
• Since event 2 I'm stuck in a downward spiral, my body over-reacts to nearly everything

Possible mechanisms I'm considering:

• MCAS-light / mast cell hyperreactivity
• Hyperadrenergic POTS (vasodilators tip the system over)
• H₂S overproduction via dysbiotic microbiome (Bilophila wadsworthia at upper limit) — would explain NAC reaction through sulfur metabolism
• Reductive stress (my GSH/GSSG ratio was 44, norm 10–15)

My questions for you:

1. Has anyone reacted to NAC at a normal dose like this? Near-syncope, energy crash, long after-effect?
2. Has anyone experienced a supplement cocktail on empty stomach that led to ER? What was it for you?
3. Who has discovered the connection dysbiotic microbiome + sulfur/H₂S sensitivity for themselves? What helped?
4. Who has come out of a hyperreactive state after a crash like this, and how?

Thanks for any shared experience.

Tipps zum Posten

Was diese Posts besonders gut machen werden:

• Die NAC-Reaktion bei normaler Dosis ist sehr spezifisch – das wird in MCAS-/POTS-Subreddits Reaktionen ziehen, weil viele Menschen genau das erlebt haben und es selten thematisiert wird
• Die Bilophila/H₂S-Verbindung ist Insider-Wissen – wer das versteht, ist wahrscheinlich erfahren genug, dir wirklich zu helfen
• Die Kombination dokumentierte Dysbiose + hyperreaktiv ist konkret genug, dass Leute mit ähnlichem Mikrobiom-Profil sich erkennen

Hi everyone,

I'm looking for people with similar experiences because my picture has no clear label from doctors yet.

Quick about me: 28, female, underweight (BMI 17.5), sick at varying intensities for 4 years, currently in a bad phase.

My story:

• March 2022: severe COVID (3 weeks)
• 2022–2023: flu-like infections every 2–3 months
• July 2024: after antibiotics for bronchitis, the real trouble started — abdominal pain after every meal, skin reactions, sneezing, fatigue
• Diagnosed: severe gut dysbiosis (Akkermansia 0 %, all neuroactive species 0 %) + candida overgrowth
• Several ER visits for "allergy-like" reactions (IgE tested negative)

What worked:
Over about 6 months I consistently worked with baobab powder, L-glutamine and probiotics. Step by step it got better — by the end no more histamine reactions, just occasional mild abdominal pain. I could eat normally again.

Where it went downhill:
After feeling better I stopped the supplements. Some time later I wanted to restart them. After one supplement cocktail (several things at once, partly on an empty stomach) my body shut down completely within one day — it felt like poisoning, I ended up in hospital.
Since then I've been stuck in a downward spiral. My system over-reacts to almost any substance and any intervention.

Current main symptoms:

• Extreme fatigue, can't manage daily life
• Low BP, dizziness, near-syncope on standing
• Brain fog (since adolescence, now much worse)
• Internal body tremor / vibrations, "stress surges" with no trigger, dilated pupils
• New: joint, leg and back pain
• Reproducible reactions to walnuts, cocoa, fermented foods, high-histamine foods

What's already documented:

• Severe post-antibiotic gut dysbiosis
• Elevated plasma histamine (tryptase normal, IgE neg → not classic MCAS)
• DEXA: osteoporosis-range at femur (at age 28!)
• Sarcopenic threshold (very low muscle mass)
• Recurring mild metabolic acidosis without clear cause
• 4 hospital presentations in 6 months with stress-pattern bloodwork but no infection

What doctors say:
"Stabilize first" — but without a concrete plan. Nobody knows how to get me out of this hyperreactive state.

Suspected hypotheses (from my own research):

• Post-antibiotic dysbiosis (confirmed) as original trigger
• MCAS-light / mast cell hyperreactivity (re-triggered by the crash)
• Hyperadrenergic POTS
• hEDS spectrum (S-scoliosis, low BP, brain fog since youth, thin corneas)
• RED-S from chronic underweight

My questions for you:

1. Has anyone been through this exact arc — slow stabilization with a targeted protocol → stopped supplements → crashed when trying to restart?
2. How do you get out of a "my-body-reacts-to-everything" state when every intervention triggers a reaction?
3. What strategy got you back on solid ground after a crash like this?
4. Who has found a good specialist for this combination (dysbiosis/MCAS/POTS/hEDS) — in Europe or Asia?

Thanks for any shared experience — even if only one piece resonates.

Hi zusammen,

ich suche nach Menschen mit ähnlichen Erfahrungen, weil mein Bild für die Ärzte bisher kein klares Etikett hat.

Kurz zu mir: 28, weiblich, schlank (BMI 17,5), seit 4 Jahren in wechselnder Intensität krank, aktuell in einer schlechten Phase.

Meine Geschichte:

• März 2022: schwerer COVID-Verlauf (3 Wochen)
• 2022–2023: alle 2–3 Monate grippeähnliche Infekte
• Juli 2024: nach einer Antibiose wegen Bronchitis ging es richtig los – Bauchschmerzen nach jedem Essen, Hautreaktionen, Niesen, Erschöpfung
• Oktober 2025: Diagnostiziert: schwere Mikrobiom-Dysbiose (Akkermansia 0 %, alle neuroaktiven Spezies 0 %) + Candida-Befall
• März 2026: Einnahme div. Supplements auf nüchternen Magen (Baobap-Pulver, L-Glutamin, Vitamin C, Probiotika) -> Krankenhaus Aufenthalt (Ursache Unklar)

Was funktioniert hat:

Über etwa 6 Monate habe ich mit Baobab-Pulver, L-Glutamin und Probiotika gearbeitet. Es wurde zunehmend besser – am Ende keine Histamin-Reaktionen mehr, nur ab und an leichte Bauchschmerzen.

Januar 2026: 4 Wochen nahezu symptomfrei, konnte alles essen, hatte Energie.

Was den Rückfall ausgelöst hat:

Bauchschmerzen und Histamin-Reaktionen kamen zurück. Ich habe versucht, die gleichen Supplements wieder zu nehmen, und bin innerhalb eines Tages im Krankenhaus gelandet – es fühlte sich an wie eine Vergiftung. Seitdem stagniert mein Körper, mein System reagiert auf nahezu alles über.

Aktuelle Hauptsymptome:

• Extreme Erschöpfung, Alltag kaum möglich
• Niedriger Blutdruck, Schwindel, Kopfschmerzen
• Brain Fog
• Vibrieren im Körper, „Stress-Surges" ohne Auslöser, erweiterte Pupillen
• Neu: Gelenk-, Bein- und Rückenschmerzen (unklar, ob es an meiner skoliose liegt oder weil ich seit Wochen mich nicht bewege und im Bett liege)
• Blutzuckerprobleme
• Schlechter Schlaf. Kann aktuell nur mit Supplements (Gaba+Magnesium+Melatonin schlafen).

Was bereits dokumentiert ist:

• Schwere postantibiotische Mikrobiom-Dysbiose
• Plasma-Histamin erhöht (Tryptase normal, IgE neg → kein klassisches MCAS)
• DEXA: Osteoporose-Bereich am Femur (mit 28!)
• Sarkopenie-Schwelle (sehr wenig Muskel)
• Wiederkehrende leichte metabolische Azidose ohne klare Erklärung
• 4 Klinikvorstellungen in 6 Monaten mit Stress-Blutbild ohne Infekt

Was die Ärzte sagen:

„Erst stabilisieren" – aber ohne konkreten Plan. Seit dem letzten Krankenhausbesuch reagiert mein Körper auf nahezu jedes Supplement und jede Intervention überschießend. Es wurden schon sehr viele Bluttests und allmögliches getestet, aber kein Arzt konnte mir bisher sagen was ich genau habe.

Verdachts-Hypothesen (aus Eigenrecherche):

• Postantibiotische Dysbiose (gesichert) als ursprünglicher Auslöser
• Hyperadrenerger POTS
• hEDS-Spektrum (S-Skoliose, niedriger BD, Brain Fog seit Jugend, dünne Hornhäute)
• MCAS-light
• RED-S durch chronisches Untergewicht

Meine Fragen an euch:

1. Erkennt jemand dieses Muster bei sich – besonders die Klima-/Hitze-Abhängigkeit?
2. Hat jemand Ähnliches erlebt: nach Antibiose krank → über Monate stabilisiert → durch einen Trigger wieder verloren?
3. Was hilft, wenn man einmal in einen „alles-reagiert-auf-alles"-Zustand gerutscht ist und der Körper die ganze Zeit im “Überlebensmodus ist”? 
4. Wer hat einen guten Spezialisten für diese Kombi (POTS/hEDS/MCAS + Dysbiose) gefunden?

Danke für jede geteilte Erfahrung – auch wenn nur ein Punkt passt.

Meine Frau ist seit einem Jahr krank. Teilweise bettlegerisch. Besserung ist nicht in Sicht. Ich als Mann versuche es so gut es geht sie zu unterstützen. Neben meiner Arbeit muss ich kochen, sauber machen und seelischen Beistand leisten und wenn ich ehrlich bin hasse ich es nur noch. Jedes Gespräch dreht sich nur noch um Gesundheit und ich verliere immer mehr die Lust mit ihr Zeit zu verbringen und mit ihr zu reden.
Ich liebe meine Frau aber ich stelle mir sehr oft die frage wie lange ich das noch aushalte. Ich hasse mich auch sehr für meine Gedanken und wünschte mir dass ich diese nicht habe und einfach positiver bin. Was würdet ihr in meiner Situation tun? Trennen ist keine Option. Das würde ich mir nicht verzeihen
