Heavy periods describe excessive menstrual bleeding that lasts more than seven days or requires a pad change more than every two hours. These heavy periods often involve the passage of large blood clots and may be accompanied by vaginal pain and fatigue.
Medically known as menorrhagia, heavy periods can lead to significant iron loss and the potential development of anemia. In some instances, heavy periods signal underlying health concerns such as uterine fibroids, hormonal imbalances, or reproductive cancers.
A gynecologist can diagnose the cause of heavy periods through specialized blood tests and pelvic ultrasounds to determine an appropriate clinical path. Treatment for heavy periods typically ranges from medications like anti-inflammatories and hormones to surgical procedures such as a hysterectomy.
Main symptoms
The main symptoms of heavy periods are:
- Abnormal and abundant blood loss, requiring a pad or tampon change more than every 2 hours
- Periods that lasts more than 7 days
- Vaginal pain
- Presence of clots during menstruation
- Abdominal swelling
- Easy fatigue
- Possible fever
Excessive bleeding during periods can also reduce hemoglobin and iron levels in the blood, which can lead to symptoms of anemia, like dizziness, paleness, headache, hair loss and lack of appetite.
Is heavy menstrual bleeding considered dangerous?
Is heavy menstrual bleeding considered dangerous? It can pose health risks if the flow is extremely heavy or continues for an extended number of days.
This condition often leads to significant iron loss, which may eventually cause anemia. Consequently, you might experience symptoms like persistent fatigue, weakness, or lightheadedness.
In some instances, heavy bleeding could signal underlying health concerns, such as uterine abnormalities or, in rare cases, cancer. Because of this, it is essential to consult with a healthcare provider for a professional evaluation.
Confirming a diagnosis
Heavy periods should be diagnosed by a gynecologist, who will assess the signs and symptoms the patient presents with.
To identify the cause of heavy periods, the doctor may order lab tests that look at progesterone, estrogen and LH levels, a complete blood count and a urinalysis. The doctor may also order an abdominal or transvaginal ultrasound to visualize reproductive organs.
Common causes
The main causes of menstrual bleeding are:
- Abnormalities in the uterus, such as fibroids, polyps, adenomyosis and cancer
- Abnormalities in blood clotting
- Hormonal problems, such as hypothyroidism or hyperthyroidism or lack of ovulation
- Infection in the uterus, urinary tract or bladder
- Use of oral contraceptives
- Pregnancy or miscarriage
Although heavy periods can affect any woman, it is more common in women who are obese, who are entering menopause or who have a family history of heavy bleeding to experience this symptom.
When it is not possible to identify the cause of excessive bleeding, it may be considered to be dysfunctional uterine bleeding. This condition does not have a specific cause, but is associated with uncontrolled growth of the uterine lining, causing bleeding and increasing the risk for endometrial cancer.
Treatment options
The treatment for heavy menstrual bleeding depends on the underlying cause of the excessive flow, and it may include several options.
1. Medication for heavy menstrual bleeding
Commonly recommended medications include anti-inflammatories like ibuprofen or naproxen, which help reduce pain and menstrual flow. Antifibrinolytics, such as tranexamic acid, are also used to decrease the volume of bleeding.
Hormonal treatments, such as combined oral contraceptive pills or levonorgestrel-releasing intrauterine devices, can help regulate the menstrual cycle and lower the total amount of blood lost. Additionally, your doctor may suggest iron and folic acid supplements to prevent or manage anemia caused by excessive blood loss.
2. Surgical treatment
When medication is not effective or there is a structural issue in the uterus, such as fibroids or polyps, surgery may be necessary. Procedures like hysteroscopy are often used to remove these growths, while endometrial ablation can be performed to destroy the uterine lining and reduce bleeding.
In more severe cases where symptoms are unmanageable or there is a risk of cancer, a hysterectomy, the surgical removal of the uterus, may be indicated.
