When to seek medical help immediately — red flags
The DiffBiome course is largely safe, and most symptoms are mild and transient. There are, however, signs at which you should not be reading a book, but seeking medical help immediately. This chapter goes through these red flags once, clearly — so that you recognise them, and know what to do.
Recurrent Clostridioides difficile infection can most often be managed at home, with the DiffBiome course and patience. Most of the symptoms that arise during treatment are mild and transient: bloating, wind, a temporary change in the stool. There are, however, signs that may conceal a serious, urgent condition — and at these you must not wait. This chapter serves a single purpose: that you know clearly which these "red flags" are, and that if you notice any of them in yourself, you seek medical help immediately, even at a hospital emergency department. This chapter is the most important safety part of the book — it is worth reading even if you are well now, because that way you will recognise trouble when it comes.
The most serious signs — hospital immediately
Some conditions require immediate hospital care, because they can be life-threatening. Such is strong, cramping or continuous abdominal pain, when your abdomen becomes tense, hard and very tender, and perhaps distended — this can be a sign of severe inflammation or dilation of the large bowel. Such is high fever, shivering, confusion or drowsiness, which may indicate that the infection has entered the bloodstream. And such is severe dehydration: if you barely pass urine, you feel dizzy, you are very weak, your mouth is dry, or you cannot keep fluids down because of vomiting.
At these signs there is no deliberating: call a doctor or an ambulance, go to the emergency department. The DiffBiome course does not replace the hospital in such cases — it is hospital care that brings you to safety.
When the stool gives a message
The stool reveals a lot about your condition. Fresh, red blood in the stool, or black, tarry stool always calls for medical attention — do not wait with it. Likewise, if the diarrhoea does not lessen but worsens day by day, with frequent, watery stools, that too is a signal. After the tenth day of the course, persistently loose, unformed stool (6–7 on the Bristol scale) may indicate that the treatment has not brought the expected response — definitely discuss this with your doctor, because the dose may need to be raised or a different preparation chosen.
The distinction is important: in the first days of the course, transient bloating, wind and mild abdominal discomfort are common and normal. The red flag is not this, but blood, high fever, a worsening, uncontrollable condition.
What to do if you see a warning sign
If you recognise one of the red flags, the thing to do is simple: do not look for an explanation, do not wait "one more day", but seek medical help immediately. Call your treating physician, or if they are unavailable and the symptom is serious, go to the emergency department or call an ambulance. Take with you — or tell them — your diary: how many days the infection has lasted, which DiffBiome preparation and what dose you are taking, which LOT, and exactly which symptoms appeared and since when. This information can speed up appropriate care by minutes.
The Clinical protocol guide v2.1 (May 2026) sets out a clear override rule: regardless of the calculated SIS score, critical signs — suspected toxic megacolon, fulminant colitis, severe dehydration, and sepsis criteria — justify immediate hospital admission. In these cases the intensive protocol belonging to the upper band (HospBiome 5(L) initiation, then 5(XX) continuation) also comes into consideration only in a hospital setting, under medical supervision.
The DiffBiome datasheet (DiffBiome Service Datasheet) divides side effects into two groups. Common and mild: gastrointestinal discomfort, bloating, flatulence, transient diarrhoea or constipation — these typically resolve on their own. Rare but serious: infection and allergic reaction — these require immediate medical assessment. Within the pharmacovigilance framework, every serious adverse event must be reported to the competent authority (EMA/FDA/local).
The Bristol scale serves for the objective monitoring of the stool (Lewis & Heaton 1997 [357]). The target state of the protocol is Bristol 3–4; a persistent 6–7 value after day 10 is classified as an inadequate therapeutic response, and may justify raising the dose (DiffBiome+) or switching the preparation. The mortality-reducing effect of FMT is documented in severe and fulminant CDI, but this is a hospital, not a home, decision (based on the FMT evidence of the v2.1 reference base).
Today you have nothing else to do but really commit the red flags to memory. Read them through twice, and put the short list on the fridge or in your phone.
- Write in a well-visible place: strong/tense abdominal pain, high fever, confusion, severe dehydration, fresh blood in the stool
- Save your treating physician's and the emergency contact in your phone
- Fluid replacement and the daily dose according to the usual routine
- Diary: stool count, Bristol, bloody stool, fever, wellbeing
Today put together a simple sheet that anyone can pick up in case of trouble — whether you or a relative.
- Write down: the onset of the infection, current DiffBiome preparation and dose, LOT number, other medications
- Put the sheet next to your diary, in an easily accessible place
- Tell a relative where to find the sheet if you become unwell
- Diary: the usual fields + any unusual symptom
Today review the week's diary from the perspective of whether any worrying sign appeared — and if so, discuss it with your doctor.
- Review: was there bloody stool, fever, worsening diarrhoea or strong abdominal pain during the week?
- If anything is yes, report it to your doctor even if it has since passed
- Confirm in your mind the difference: a mild, transient symptom vs. a red flag
- Diary: the trend of the 3 days, and the weekly summary of the warning signs
🍽️ Eating during these days
The theme of this chapter is safety and recognising warning signs — here eating works in the background, quietly, for recovery: the varied, fibre-rich plate feeds the engrafted flora and strengthens colonisation resistance. Important, however, is the distinction that the chapter also emphasises: in the first days of the course, transient bloating, wind or mild abdominal discomfort are common and normal — this can also be caused by a new, fermentable plant source — whereas bloody stool, high fever or a worsening condition are a red flag, not a response to food. The concrete eating task for the three days: keep up fluid replacement, and each day include the plant of the day in at least one meal.
For these days (82–84), the Plant Calendar (Appendix F) brings the sources linseed oil (82), pumpkin seed oil (83) and parsley leaf (84). Linseed oil provides omega-3 fatty acids, pumpkin seed oil provides zinc and polyphenols, and parsley leaf provides vitamin C and plant variety. In the second half of the programme (roughly days 61–90), the goal is to sustain full diversity and fermentable fibre sources: the more kinds of plant source and healthy fat that reach the plate, the more kinds of useful bacteria you feed, and the more short-chain fatty acids (including butyrate) form, which support the gut barrier and diversity. A diverse, stable flora is the basis of resilience — it is what makes the gut more resistant. If one of the sources causes bloating or discomfort, that is not in itself a warning sign; but if you see any of the red flags listed in the chapter, that is not an eating question — seek medical help immediately.
To recognise the red flags, track these fields with particular care:
- daily stool count (and its direction: decreasing / stagnant / increasing);
- stool Bristol scale (1–7);
- bloody stool (yes/no);
- fever (yes/no; if yes: temperature);
- abdominal pain intensity (0–5);
- signs of dehydration (amount of urine, dizziness, weakness);
- fluid intake (litres);
- wellbeing (1–5).
- Movement: type + minutes, step count (target/actual)
- Stress level (1–5) and mood (1–5)
- Sleep (hours + quality 1–5)
Do not wait if you experience any of the following: strong, cramping or continuous abdominal pain, a tense, hard, tender or distended abdomen; high fever or shivering; confusion, drowsiness; signs of dehydration (you barely pass urine, dizziness, marked weakness, dry mouth, or you cannot keep fluids down); fresh, red blood or black, tarry stool; or if you feel so unwell that you cannot get up. These require urgent medical, often hospital, care. Call your treating physician, or in a serious case go to the emergency department or call an ambulance.
Knowing the red flags is not scaremongering, but the guarantee of your safety. With the DiffBiome course most symptoms are mild and passing — but recognising the few serious signs can come down to minutes, and those minutes count. If you know what to watch for and what to do, you can move along the road of recovery with peace of mind, because you have a safety net.

The authors evaluated the responsiveness of the Bristol Stool Form Scale to changes in whole-gut transit time (WGTT). Sixty-six volunteers had WGTT measured with radiopaque markers and recorded stool form on a 7-point scale and defecation frequency; measurements were repeated under senna and loperamide. Baseline WGTT correlated with frequency (r=0.35, P=0.005) and stool output (r=-0.41, P=0.001), and best with stool form (r=-0.54, P<0.001). Senna (n=44) shortened WGTT and increased frequency, form score and output (all P<0.001); loperamide (n=43) lengthened WGTT and reduced frequency, form score and output (all P<0.001). The Bristol scale is a valid surrogate for intestinal transit time and is responsive to pharmacological alteration.
