Sepsis in IBD: what you should know
For people with Crohn's disease or Ulcerative colitis the focus is often on everyday life with diarrhea, pain or fatigue. However, serious complications can also occur - including Sepsis (often also called blood poisoning or bloodstream infection). Sepsis is an excessive immune response of the body to an existing infection. Untreated sepsis always leads to death; the earlier sepsis is treated, the greater the chance of survival. In this article we would like to explain it to you in an understandable way, what sepsis means in the context of IBD, Which risk factors play a role and How to stay mindfulwithout having to worry all the time.

What is sepsis?
Sepsis is a Excessive reaction of the body to an infectionin which the immune system attacks the body's own tissue. This can lead to multi-organ failure or serious life-threatening complications such as myocarditis or meningitis. After surviving sepsis, around 75% of all survivors experience late effects such as amputations, cognitive impairment, fatigue and polyneuropathy. The consequences are manifold and vary from patient to patient.
Why is sepsis relevant in IBD?
A systematic analysis of intensive care recordings at the Technical University of Munich has shown: CED-specific complications (such as perforation or electrolyte imbalance) and Septic courses are among the most common reasons for inpatient intensive care treatment. It becomes particularly critical when sepsis occurs in conjunction with ongoing immunosuppression.
What are possible triggers for sepsis in IBD?
z.e.g. in the case of perforations or fistulas
that can weaken the body's own defenses
such as Candida sepsis, pneumocystis or varicella pneumonia
Who is particularly at risk of sepsis?
The TU Munich analysis identified risk factors such as:
- Older age at initial diagnosis or intensive care admission
- Previous operations on the bowel
- Crohn's disease as an underlying disease
These factors were more frequently associated with a severe course or increased mortality.
What are the signs of sepsis?
For people with ulcerative colitis or Crohn's disease, there are clear medical recommendations for Early detection. In both cases, the regular Colonoscopy (colonoscopy) regardless of whether acute symptoms are present or not.

What can I do to recognize sepsis in IBD at an early stage?
Important:
The decision about immunosuppressive drugs is always individual - in certain cases they are essential for disease control. However, the data shows that careful patient selection and close monitoring are crucial for safety.
Conclusion
Sepsis is a potentially life-threatening complication that can occur in severe infections - regardless of the underlying disease. If you have IBD, you should remain vigilant, especially if you have a fever, chills or unusual weakness. If you are well informed, know your symptoms and work closely with your medical team, you can minimize the risk. It's not about fear - it's about Knowledge that strengthens.

Microbiome as the key - new therapy for Crohn's disease
Crohn's disease is a chronic inflammatory bowel disease (IBD) that affects the lives of millions of people worldwide. One proven therapy is the so-called Exclusive enteral nutrition (EEN) - a special liquid diet that patients consume for six to eight weeks instead of solid food. This method has proven to be extremely effective, but why it helps was previously unclear.

Therapeutic approaches for Crohn's disease based on the S3 guideline
The treatment of chronic inflammatory bowel disease is difficult and depends on the individual patient. Severity of the disease from. Crohn's disease and ulcerative colitis are two of the most widespread chronic inflammatory bowel diseases. Crohn's disease can affect the entire gastrointestinal tract, i.e. it can begin in the oesophagus and extend to the anus.

Therapy for ulcerative colitis - current treatment approaches based on the S3 guideline
The treatment of ulcerative colitis (UC) has several objectives. Firstly, the inflammation in the intestine should be reduced and secondly, the symptoms should be alleviated. The therapy also aims to achieve long-term remission. Ideally without the use of corticosteroids. What treatment options are there and how are they individually adapted based on the course and severity of the disease?
