Suffering from heavy bleeding? Find out the 10 causes of Heavy Periods.
It’s often difficult for women to recognise whether their bleeding is abnormal.
That’s because menstrual patterns vary significantly between women.
Here we discuss “what is a normal period?”, how to recognise excessive menstrual bleeding, and the 10 causes of heavy menstruation.
What is a normal period?
What is an abnormally heavy period?
- Bleed for longer than 1 week
- Need to change your pad or tampon very frequently during your period
- Pass large amounts of clots
- Feel that your lifestyle/activities are restricted due to your bleeding
- Have symptoms of anaemia – tiredness, weakness, giddiness, breathlessness, chest discomfort
Menorrhagia is not to be taken lightly! If you have these symptoms, seek help from a doctor.
10 causes of heavy menstruation
Why is my period so heavy?
1. Hormonal imbalances
Menstruation occurs due to the complex interaction between several hormones within the female body. If these hormones are imbalanced, heavy bleeding can occur. Multiple factors impact on your hormones; these include lifestyle, stress, illness and medication use.
Growths within the walls of your womb (uterus) are called fibroids. They occur commonly amongst pre-menopausal women, and can cause heavy or prolonged bleeding.
Small areas of tissue growth from the surfaces of your womb (uterus) or cervix can be sensitive, and prone to bleeding. This can take the form of heavy bleeding during the period, in between periods (inter-menstrual bleeding), or bleeding after sex.
The endometrium is the lining of the womb that develops during each menstrual cycle, and is shed during the period. Abnormal, excessive growth of endometrial tissue can result in heavy bleeding, and painful periods.
Whilst rare, heavy menstrual bleeding can sometimes be due to cancer of the cervix, uterus, endometrium, or ovaries.
An ectopic pregnancy occurs when the fertilised egg implants in an area outside the uterus, usually along the Fallopian tube. Ectopic pregnancy, along with miscarriage, are pregnancy related complications that can cause a delayed period and heavy menstrual bleeding.
7. Bleeding disorders
Heavy bleeding may result due to disorders of the blood clotting system. These conditions are usually inherited, and carried within families. Ask your family members about a history of abnormal bleeding, if you are experiencing heavy periods.
Certain medications that are taken to treat other conditions such as heart disease, stroke, or previous blood clots can all result in thinning of the blood and contribute to heavy bleeding.
9. Sexually Transmitted Diseases (STDs)
STDs can lead to a more serious condition known as pelvic inflammatory disease (PID), which is associated with heavy bleeding. Other symptoms of STDs or PID include bleeding after sex, abnormal vaginal discharge, vaginal itching, lower abdominal pain, and pain during sex.
10. Other medical conditions
Kidney, liver or thyroid disease can also interfere with your menstruation and cause excessive menstrual bleeding.
If you’re experiencing heavy bleeding, don’t ignore it.
Prolonged heavy bleeding can eventually lead to a low blood count, which can be dangerous.
Consult a doctor to find out more about investigations and treatment.
