Uterine polyps are growths that develop from the inner lining of the uterus. When these polyps form near the internal os—the opening that connects the uterine cavity to the cervical canal—they may be called “internal os polyps. Uterine polyps are small, often benign (non-cancerous) growths that form on the lining of the uterus (endometrium). They can vary in size from a few millimeters to several centimeters. When these polyps are found at or near the internal os, they might affect the flow of menstrual blood or cause other symptoms.
The internal os is the internal opening of the cervix into the uterus. It plays a key role in controlling the flow of menstrual blood and in maintaining a pregnancy by keeping the uterus closed. Although many uterine polyps are benign, they can cause irregular bleeding, pain, or even fertility issues. In some cases, they may require treatment to relieve symptoms or prevent complications.
Pathophysiology
Understanding the structure, blood supply, nerve supply, and functions of the uterus and its internal os is important to know how polyps form and affect the body.
Structure
- Uterine Lining (Endometrium):
The inner wall of the uterus where polyps typically develop. The endometrium thickens and sheds during each menstrual cycle. - Internal Os:
The narrow opening of the cervix inside the uterus. It acts as a gatekeeper for menstrual flow and sperm entry. - Polyps Formation:
Polyps develop when there is an overgrowth of the endometrial tissue. They can be pedunculated (attached by a stalk) or sessile (broad-based).
Blood Supply
- Main Arteries:
The uterus is primarily supplied by the uterine arteries. These vessels provide oxygen and nutrients to the endometrium. - Vascularity of Polyps:
Polyps are usually rich in blood vessels, which is why they may cause heavy bleeding during menstruation.
Nerve Supply
- Innervation:
The uterus receives nerve signals from the autonomic nervous system. This nerve supply helps regulate muscle contractions and blood flow. - Pain Signals:
When polyps cause irritation or inflammation, the nerve supply can trigger pain or discomfort.
Functions
- Reproductive Role:
The uterus, including the internal os, is crucial for menstruation, implantation of a fertilized egg, and pregnancy. - Barrier Function:
The internal os acts as a barrier, helping protect the uterus from infections and regulating the flow of fluids. - Hormonal Regulation:
The endometrium responds to hormones such as estrogen and progesterone, which help regulate its growth and shedding.
Types of Uterine Polyps
While uterine polyps are generally grouped together, they can be classified based on location, appearance, and tissue type:
- Endometrial Polyps:
Develop within the uterine cavity. - Cervical Polyps:
Form on the cervix but sometimes near the internal os. - Fibroepithelial Polyps:
Contain both fibrous tissue and glandular elements. - Hyperplastic Polyps:
Linked to an overgrowth due to hormonal imbalance. - Atypical or Precancerous Polyps:
Rarely, polyps can show changes that may lead to cancer. - Multiple Polyps:
Some women may have more than one polyp at a time. - Pedunculated Polyps:
Attached by a narrow stalk, making them more mobile. - Sessile Polyps:
Have a broad base and are more fixed in place.
Causes
Polyps in the uterine region, including those near the internal os, can be caused by many factors. Here are 20 potential causes or risk factors:
- Hormonal Imbalance:
Excess estrogen can promote the growth of polyps. - Age:
Polyps are more common in women over 40. - Obesity:
Excess body fat can increase estrogen levels. - Hypertension:
High blood pressure has been linked to a higher risk. - Tamoxifen Use:
This drug, used in breast cancer treatment, may lead to polyp growth. - Infertility Treatments:
Hormonal stimulation in fertility treatments can cause overgrowth. - Genetic Predisposition:
Family history may increase the risk. - Chronic Inflammation:
Ongoing inflammation in the uterus can contribute to polyp formation. - Diabetes:
Metabolic changes associated with diabetes may increase risk. - Polycystic Ovary Syndrome (PCOS):
PCOS often causes hormonal imbalance. - Endometrial Hyperplasia:
A condition of thickened endometrium that can lead to polyps. - Repetitive Menstrual Cycles:
Long-term menstrual cycle irregularities can be a factor. - Nulliparity:
Women who have never been pregnant may have a higher risk. - Estrogen Replacement Therapy:
Postmenopausal hormone therapy can sometimes lead to polyps. - Smoking:
Tobacco use may contribute to hormonal changes. - Environmental Factors:
Exposure to certain chemicals or endocrine disruptors. - Infections:
Chronic pelvic infections can lead to changes in the uterine lining. - Stress:
High stress levels may indirectly affect hormone levels. - Lifestyle Factors:
Poor diet and lack of exercise may contribute to overall hormonal imbalance. - Previous Uterine Surgery:
Scarring from surgery may alter endometrial growth patterns.
