Why does lower abdominal pain occur before the period?
Lower abdominal pain before menstruation is usually due to hormonal changes. Prostaglandins, hormone-like messengers, promote uterine contractions to shed the lining. If these contractions are particularly strong, they can cause cramp-like pain. Additionally, the falling progesterone level means the muscles no longer relax, which intensifies the pain. Other factors such as bloating, digestive issues, or water retention can also create pressure in the lower abdomen, which is perceived as painful.

PMS or endometriosis? When lower abdominal pain should be evaluated
Lower abdominal pain is typical for PMS, but can also be a sign of endometriosis, a condition where tissue similar to the uterine lining grows outside the uterus. While PMS pain usually occurs shortly before the period and subsides with its start, endometriosis pain is often independent of the cycle and especially severe during menstruation. If the pain is chronic, unusually severe, or accompanied by other symptoms such as pain during sex or heavy bleeding, medical evaluation should be sought.

Which painkillers work best for PMS-related lower abdominal pain?
Nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen and diclofenac are the most common painkillers for treating PMS-related lower abdominal pain.

Which hormones cause PMS lower abdominal pain?
PMS lower abdominal pain is mainly triggered by hormonal fluctuations in the second half of the cycle. Especially Prostaglandins, progesterone, and estrogen play a crucial role.

|
Prostaglandins |
Regulate inflammation and trigger uterine contractions |
Increased levels intensify cramps and lower abdominal pain |
|
Progesterone |
Relaxes the uterine muscles and has a calming effect |
Drops sharply just before the period, causing contractions to increase |
|
Estrogen |
Promotes cycle stability and influences serotonin levels |
A drop can increase pain sensitivity |
Prostaglandins are particularly important because they control the contractions of the uterus to shed the lining. When the level is too high, the contractions become more painful and intense. Women with severe PMS lower abdominal pain often have increased prostaglandin production.
The drop in progesterone further intensifies the symptoms. This hormone usually relaxes muscles, but shortly before menstruation, it rapidly decreases, causing the uterus to react more strongly.
Also Estrogen plays an indirect role, as it is linked to serotonin levels. A low estrogen level can Pain sensitivity increase and intensify PMS symptoms.
