Thin Endometrium: Causes & Consequences

The uterus is a muscular organ of the female reproductive system that carries the fetus throughout the course of a woman’s pregnancy and is made up of three layers: the innermost, middle, and outer layers. The deepest layer of the uterus is called the endometrium. A healthy, thick optimum endometrium is essential for a normal menstrual cycle and a smooth pregnancy. The uterine lining is another name for endometrium. In addition, thick endometrium greatly facilitates the successful implantation of fertilized eggs inside the uterus. For the fetus to be successfully implanted, the uterine lining must be at least 8 mm thick.


Later on, during pregnancy, it also provides the fetus with nourishment, allowing it to develop. Two hormones produced by the ovaries thicken and prepare the uterine lining for implantation: progesterone and estrogen. Progesterone supplements are used to prepare for the transfer of an embryo into the uterine cavity, whereas estrogen plays a significant role in keeping the endometrium blood-rich, healthy, and thick. Various clinical examinations have seen that assuming that a lady has diligently slim uterine coating, the opportunity for pregnancy is less regardless of whether there is sufficient estrogen. An endometrial lining that is thin can be caused by five main factors.

  • Low levels of estrogen:

Lack of estrogen is the primary cause of a thin endometrial lining. A blood test can be used by your doctor to see if your body has an adequate amount of estrogen. Tablets, injections, or patches can be used to replenish your estrogen level if it falls below the normal range.

  • Endometrial lining damage:

A previous uterine infection that damaged the uterine lining and resulted in the formation of scar tissue may be the cause of a thin endometrial lining despite the presence of adequate estrogen.

  • Reduced flow of blood:

Insufficient blood flow to the endometrium may result in thinning of the lining, although this is not a typical cause of thin endometrium. An ultrasound that measures blood flow to the uterus can be used by your doctor to check for this.

  • Fibrous uteri:

The benign growths that occur in the uterus are referred to as uterine fibroids. They can be either little to such an extent that they can’t be seen by the natural eye or sufficiently huge to cause swells in the uterus.

  • Endometritis that persists:

The infection of the endometrial cells that causes inflammation of the uterine lining is known as chronic endometritis. Despite the fact that it is not a life-threatening infection, it is essential to receive treatment as soon as possible. Antibiotics may be prescribed by your doctor. In the event that it is chronic, you may require hospital bed rest and intravenous fluids.

In the event of in vitro fertilization, your doctor will examine your endometrial lining to ensure the best possible chance of pregnancy.


Problems with infertility

Menstrual irregularities • If they have problems getting pregnant because of thin endometrium, like not being able to conceive or having trouble keeping a pregnancy going, they need to have their estrogen level and endometrium thickness checked. For the fetus to be successfully implanted, the uterine lining must be at least 8 mm thick. If the lining of the uterus is thin, implantation fails failure, leading to a failed pregnancy. Therefore, in order to conceive, one must receive treatment for thin endometrium.
