Periods and Eating Disorders

Have you noticed changes in your period since struggling with food or weight? You’re not alone. Many people with eating disorders experience irregular or missing cycles — and your body is trying to tell you something important.

What is Amenorrhea?

Amenorrhea refers to the absence of menstruation. There are two types:

• Primary amenorrhea: when a person has never started their period

• Secondary amenorrhea: when a period stops for three or more months after previously being regular

While amenorrhea is common among people with eating disorders, not having it doesn’t mean your ED isn’t serious.

Other Menstrual Cycle Disturbances

Eating disorders can also cause:

• Irregular cycles

• Longer or shorter cycles

• Lighter bleeding

• Missed or delayed periods

• Changes in PMS or menstrual symptoms

  
  

Even if you still menstruate, these changes may indicate hormonal imbalances caused by inadequate energy intake, restriction, over-exercising, purging or being outside your body healthy weight/ fat % range.

Why Do These Changes Happen?

Your body prioritises survival. When there is not enough energy/nutrients or fat stores it starts turning off functions that are not "essential" for your survival.

One of the first things that it may shut off is the menstrual cycle. The more depleted the body becomes the more essentials functions are affected- eventually shutting off the brain and heart.

Additionally behaviors like binge–restrict cycles, purging, or excessive exercise can disrupt hormones that regulate the menstrual cycle.

The Role of Weight Bias in Healthcare

Unfortunately, weight bias is common in the medical field. People with eating disorders who aren’t underweight may be misdiagnosed with conditions like PCOS or insulin resistance.

In some cases, doctors may even suggest further restriction or weight loss — which can worsen the eating disorder.

This is why it is extremely important to work with an ED-informed, weight-inclusive healthcare team

Consequences of Menstrual Disturbances

Changes in your cycle aren’t just about fertility. They can also affect:

• Bone health

• Hormonal balance

• Metabolism

• Overall long-term health

  
  

Your body is signaling that it needs more energy and support.

Supporting Recovery

Recovery involves giving your body what it needs to feel safe:

• Eating regular, balanced meals

• Ensuring adequate energy intake

• Reducing over-exercising and purging

• Working with an ED-informed, weight-inclusive healthcare team

Remember:

• Losing your period doesn’t define your ED severity

• Getting your period back doesn’t mean you’re fully recovered

• People who don’t menstruate can still struggle with EDs
