What is secondary amenorrhea?

Amenorrhea (pronounced uh-men-o-REE-uh)  refers to the lack of periods or menstruation. There are a few types of amenorrhea, the first is primary amenorrhea which refers to someone not menstruating by the age of 15, and another called secondary amenorrhea which is what we’ll be talking about here.

Secondary amenorrhea is when someone has previously menstruated (gotten their period) but has missed 3 or more periods in a row. Periods are mostly controlled by hormones and any significant hormonal changes can cause them to increase, decrease, or stop completely.

Our hormones can be affected by all sorts of things ranging from our diet, to our stress levels, to what medications we take, and even certain medical conditions. This post will talk about some of the more common causes, and what sort of symptoms to look out for. 

Symptoms

Although everyone experiences symptoms differently, and many symptoms of amenorrhea can be caused by other issues, some common ones to look out for are:

What causes secondary amenorrhea?

It’s also possible for periods to stop due to a structural issue like a blockage of the pathway menstrual blood exits through. These are usually because of genital tract defects like an imperforate hymen (a hymen with no opening) or vaginal septum (a barrier that separates the vagina into two canals)

How do you treat secondary amenorrhea?

What to do depends on the underlying cause. In most cases, it’s recommended to see a clinician so they can figure out the issue. First, they will likely rule out pregnancy, then, clinicians will gather as much of your medical history as necessary and conduct a thorough physical examination (blood tests, pelvic exam, MRI, etc.)

Depending on the cause they find, clinicians may provide birth control pills or other hormonal medication to reset the menstrual cycle, or prescribe other medications to rebalance your hormones.
