Explanation

Heavy periods, also known as heavy menstrual bleeding, can have several causes.

Hormonal Imbalances: Sometimes, the body makes too much or too little of certain hormones that control the menstrual cycle. This can lead to heavy bleeding.

Bleeding Disorders: Some people have bleeding disorders that make them bleed more easily. This means they might have heavier periods.

Structural Problems: There could be issues like fibroids or polyps in the uterus that cause heavy bleeding. Endometriosis can also cause heavy periods.

In adolescents, heavy periods might be normal as their bodies are still adjusting, but it can also be a sign of a bleeding disorder. It’s important to talk to a doctor if heavy periods are causing problems, like making someone feel very tired or weak.
