Endometriosis: understanding pain (inflammation, nerves and body)
There's no single cause of endometriosis pain. Inflammation, nerves and the nervous system all play a role. Understanding these mechanisms helps us to better manage pain on a daily basis.
Endometriosis: understanding pain (inflammation, nerves and body)
The pain associated with endometriosis is complex. It comes not just from visible lesions, but from a set of mechanisms involving inflammation, nerves and the nervous system.
This is why :
- some people have a lot of pain with few lesions
- others have little pain despite significant lesions
Understanding these mechanisms enables us to better manage pain and adapt our solutions.
1. Inflammation: a key driver of pain
Endometriosis is a chronic inflammatory disease.
Endometriosis lesions :
- react to hormones
- bleed with each cycle
- provoke an inflammatory reaction
This inflammation can lead to :
- intense menstrual pain
- burning or tightness
- severe fatigue
- digestive pain
Why inflammation hurts
Inflammation releases substances called prostaglandins.
They cause :
- uterine contractions
- spasms
- pain
This mechanism also explains menstrual cramps.
2. Adhesions and mechanical tension
Over time, inflammation can lead to adhesions.
Organs can then :
- "stick together
- lose mobility
- create internal tensions
This can lead to :
- chronic pain
- pain during movement
- pain during intercourse
- sensation of tightness
3. Nerves: amplified pain
Endometriosis can affect the nerves in several ways:
- irritation of nerves by inflammation
- presence of nerve fibers in lesions
- compression due to adhesions
This can lead to :
- more intense pain
- radiating pain (back, legs)
- burning or discharge sensations
- persistent pain even outside the period
In some cases, the pain becomes partially "neuropathic".
4. The nervous system: a key role
When pain lasts over time, the nervous system can become more sensitive.
This is sometimes referred to as "sensitization".
This means that :
- the pain threshold decreases
- the body reacts more strongly
- pain can become chronic
The nervous system can then :
- amplify pain signals
- maintain pain even without significant stimulation
Important: This does not mean that pain is "psychological". It is real, but the nervous system is involved in amplifying it.
5. The role of hormones
Hormones have a direct influence on pain.
- estrogen stimulates lesions
- the drop in hormones before menstruation can increase inflammation
This is why :
- pain is often worse during menstruation
- some people also feel pain before or after their period
6. The link with digestion
Endometriosis can affect or influence the digestive system.
This can cause :
- bloating
- abdominal pain
- transit problems
- discomfort after meals
Inflammation and internal stress can also disrupt the microbiota.
7. Why fatigue is often present
Fatigue is common in endometriosis.
It may be linked to :
- chronic inflammation
- constant pain
- disturbed sleep
- energy used to manage pain
It's not "in your head", it's physiological.
8. Why pain is different for everyone
Everyone's experience is different, because pain depends on :
- the location of lesions
- the intensity of inflammation
- nerve involvement
- the sensitivity of the nervous system
- stress level
- lifestyle
There is no single form of endometriosis.
9. What can help reduce pain?
Understanding the mechanisms of pain helps us to act on a number of levers.
Reducing inflammation
- anti-inflammatory diet
- omega-3
- limit ultra-processed products
Relax muscles and relieve tension
- heat (hot water bottle, hot bath)
- stretching
- yoga
Act on nerves and nervous system
- breathing
- relaxation
- stress management
- sleep
Improve mobility
- gentle physical activity
- specialized physical therapy
Medical treatment
- hormonal treatments
- analgesics
- specialized follow-up
Things to remember
Endometriosis pain is multifactorial.
It involves :
- inflammation
- adhesions
- nerves
- nervous system
- hormones
That's why a global approach is essential.
Understanding these mechanisms enables you to :
- listen better to your body
- relieve guilt
- find appropriate solutions
- improve quality of life
