Heavy blood clots and bleeding for several weeks with clots the size of a persons liver what causes it and can it be fatal?

Answer 1

Whenever you have a case of prolonged vaginal bleeding it is important to seek medical attention.

What you have described could be a symptom of several conditions.

You could be experiencing breakthrough bleeding caused by an imbalance in hormones (this usually only happens when you're using certain forms of hormonal birtcontrol), the bleeding can vary from just spotting to heavy bleeding but usually stops in a few weeks and is very little to worry about.

I see that you categorized this question as one pertaining to miscarriage. It is possible that you're miscarrying. When a miscarriage occurs the body has to eliminate all the tissue associated with the pregnancy (which could possibly be what you described as large blood clots). With a miscarriage you may also notice grayish tissue being passed as well, this is fetal tissue (what would have been the baby), however this is not seen in all miscarriages, it all depends on how far along the pregnancy was when the miscarriage occurs. Bleeding associated with a miscarriage generally only lasts for about 2 weeks and will vary from heavy to very light, the heavy bleeding will usually be accompanied by intense cramping.

Whatever it is, passing large blood clots is something to worry about. This could be a sign of ovarian cysts cancer, and various other infections of the uterus. I would not say that you are necessarily in danger of dying, but please, seek medical attention as soon as possible.

As I stated before, any time you have a case of prolonged vaginal bleeding, especially if you're experiencing any pain or discomfort, you should always talk to a doctor. Bleeding for that long is not natural and unusually is a sign that there is something wrong.
