Endometriosis does not endanger the life of the patient but causes many difficulties in life as well as affects the fertility of women, this is a disease quite a lot of women encounter today.

1. What is endometriosis?

Endometriosis is a condition in which tissue located inside the uterus of the person develops to the outside of the uterus and encroaches on both the ovopian tubes and is often found in the pelvis or abdomen. They can grow and encroach on other bodies, such as the ovate or ovaries. Like other normal uterus tissues, these improperly developed tissues accumulate and peel off according to the patient's menstrual cycle. But over time, tissues that grow outside the uterus prevent blood from flowing out of the body but accumulate, causing internal bleeding and infections or cysts.

Endometriosis is usually associated with the ovulation, ovaries, intestines or tissues in the pelvic floor. The surrounding endotriosis tissues can be irritated and cause the person to feel pain, forming scar tissue and bags containing fluid that make it difficult for you to spawn.

The classification and determination of the stage of endometriosis is based on a number of factors, such as location, depth, size and number of tissues.

2. Symptoms of endometriosis

The most common symptom of endometriosis is pain in the pelvis, usually during menstruation. The person may also feel pain during sex, bowel movements, and when urinating. Other symptoms include fatigue, diarrhea, constipation, flatulenceand nausea.

In addition, some common symptoms in patients with other endometriosis include:

  • Pelvic pain during menstruation and worsening pain over time
  • Feel lumbar pain and abdominal pain;
  • Pain during or after sex;
  • Pain during urination, urination when it comes to menstruation;
  • Longer menstrual cycles or more bleeding
  • In the stool or urine there is blood, vaginal bleeding after sexual contact;
  • Constipation, diarrhea, flatulence, fatigue, vomiting or nausea, especially during menstruation;
  • Feel pain during menstruation;
  • Infertility

Mostly, the stages of endometriosis do not affect the symptoms of the disease. For example, a person with stage 1 endometriosis may experience more severe pain than a person at stage 4, with the exception of infertility. Women with endometriosis at stage 3 or 4 are more likely to have difficulty getting pregnant than those with the disease at stage 1 or 2.

The person may experience some other symptoms of the disease. If you have any questions about the signs of illness, you should consult a doctor.

3. Stages of endometriosis

There are different ways to diagnose endometriosis. According to the American Society for Biological Medicine, doctors determine the stage of endometriosis based on the spread of endometrial tissue, its depth and the areas of the patient's body affected by this unusual development.

Based on the above factors, endometriosis is classified into 4 stages:

  • Stage 1: Small size and number of endometriosis mass. They can be found on other organs of your body, such as the pelvic or abdominal area. There is little or no scar tissue.
  • Phase 2: The length and depth of transplantation of the endoratometrial is longer at stage 1. They are also deeper in the tissue and may appear some scar tissue.
  • Stage 3: At this stage, the transplant depth of the endoratometrial takes place more and more severely. Patients may also appear small cysts on one or both ovaries and thick strips of scar tissue called adhesives .
  • Stage 4: This is the heaviest stage. Many implants are deep and thickly adhesion. There are also large cysts on one or both ovaries.

Endometriosis does not always go from one stage to the next. If not treated, the condition may remain the same over time. Or it could get worse or better.

4. Classification of endometriosis

Endometriosis is also determined based on which area of the pelvis or abdomen it affects. Endometriosis is classified into 4 main types, including:

  • Endometrial stenosis: The peritoneum is a thin membrane lining your abdomen and pelvis. It also includes most of the muscles in these compartments . In this type, endometrial tissue attaches to theitonee. This is the least serious condition.
  • Endometriosis: These are cysts that contain old blood. They are also called chocolate cysts. They are different in size and can appear in different parts of the pelvis or abdomen of the sick person, but most commonly in the ovaries.
  • Deep-penetrating endometriosis (DIE): In this type, endometrial tissue has invaded organs inside or outside the pelvic cavity of the person. This may include the ovaries, rectum, bladder and intestines of the person. This is rare, but sometimes a lot of scar tissue can link other bodies. However, this happens only with 1%-5% of people with endometriosis.


Although endometriosis is a congenital disease, not all cases cause infertility
  • Endometriosis abdominal wall: In some cases, endometrial tissue may develop on the abdominal wall. Cells that can be attached to surgical incisions.

There is no way to prevent endometriosis. However, patients should not be too worried about the disease because not all cases of endometriosis cause infertility. For the most part, endometriosis only brings pain to the person when it comes to menstruation. When you see any signs of the disease, you should go to a reputable medical facility for timely diagnosis and treatment.
