What are the causes of abdominal pain in menstrual cramps?

Menstrual cramps are very common in women of childbearing age. It is estimated that 4 out of 5 women experience menstrual cramps of varying intensity before, during or after their menstrual cycle. In most women, it occurs 6 months after the first menstrual period and can be intermittent. The way dysmenorrhoea or menstrual cramps occur has many pathophysiological mechanisms.

We will look at each of these mechanisms and divide the causes into 2 main groups:

Primary dysmenorrhoea

This accounts for 5-15% of all dysmenorrhoea or menstrual cramps and usually causes very severe pain. Most women who suffer from it tend to miss work or school. They are caused by:

  • Excess prostaglandins: Prostaglandins are substances that are released in the human body and have various functions. One of them is the contraction of smooth muscle, which is essential in menstrual cycles for the removal of uterine lining debris. In some women, however, the release is excessive and therefore leads to sudden and very strong uterine contractions.

Secondary dysmenorrhoea

They are the most heterogeneous group of diseases that usually cause menstrual cramps, which include the following

  • Endometriosis: This is a condition in which the lining of the uterus grows abnormally. This tissue can be outside the uterus and sometimes outside the pelvic cavity. It also causes very painful periods, heavy bleeding and in many cases infertility.
  • Myomatosis: These are benign tumours that develop in the uterus and can be found in any layer of the uterus. They can cause many menstrual problems, and those in the lining of the uterus usually cause heavy bleeding. Most of them increase in size, and some may require a surgical solution.
  • Ovarian cysts or tumours: these are lesions or cysts that form on the ovaries and can cause menstrual pain. Most ovarian cysts are benign and are caused by hormonal changes during the menstrual cycle.
  • Pelvic inflammatory disease (PID): This is a fairly serious infection of the female reproductive organs. Generally, it can affect the cervix, uterus, fallopian tubes and ovaries and is usually caused by sexually transmitted infections.
  • Adenomyosis: This is an abnormal growth of the lining of the uterus that develops in the muscular walls of the uterus. They cause the uterus to enlarge during the menstrual cycle, resulting in severe menstrual cramps.
  • Cervical stenosis: Cervical stenosis is a malformation of the cervix in which the small size of the cervix prevents the normal drainage of menstrual fluid. As a result, severe menstrual cramps occur due to increased pressure in the uterine cavity.

Benefits of microwavable heat packs for menstrual cramps

For menstrual cramps and the pelvic inflammation they cause, thermotherapy is one of the best options. It offers the following benefits, among others:

  • Increases the pain threshold: Heat has significant effects on the peripheral nervous system, leading to an increase in the pain threshold. This gives the impression that the menstrual pain is much less severe.
  • Relaxes the uterus: The main function that heat produces in soft tissue is relaxation. This is because the fibres of the tissue are stretched. Since the uterus is made of smooth muscles, it responds very well to heat stimuli.
  • It relieves pain and inflammation: Heat increases the distribution of blood flow to the muscle. This gives the tissue a better supply of oxygen and nutrients, which leads to better recovery. It can therefore relieve pain and inflammation much faster.
  • Stimulates elasticity: The heat leads to more comfort and a soothing placebo effect that promotes better elasticity of the muscles. This promotes relaxation of the smooth muscles of the uterus, which helps to relieve pain.
