Missing Your Period in College? When “Healthy” Isn’t Healthy for Your Body

You’re young. You’re in college. You’re finally on your own, making your own decisions about what you eat, how you spend your time, and what you do with your body.

And then your period disappears. Maybe you don't think much of it at first.

College is stressful. Your schedule is different. You're sleeping less. You're exercising more. Maybe you lost a little weight. Maybe you've always had an irregular period anyway.

So you tell yourself it will come back. Except it doesn't.

And eventually, someone tells you something you really don't want to hear:

“You probably need to eat more and exercise less.”

And your first thought might be:

Absolutely not.

Because look around.

The girls around you are doing the opposite.

They're going to the gym every morning before class. They're taking Pilates. They're running. They're counting their steps. They're talking about protein. They're skipping breakfast because they're “not hungry.” They're ordering salads. They're eating a rice cake and calling it a snack.

And somehow, all of this has become wrapped up in the word healthy.

So now you're being told that the thing you thought was making you healthy might actually be contributing to why you don't have a period.

That can be a really difficult thing to hear.

I've worked with many women through period recovery, and one of the hardest parts is often not knowing what to do.

It's being willing to do something that feels so different from what everyone else around you is doing.

“But everyone else is doing it.”

This is one of the biggest struggles I see with college women.

You're not making your food choices in isolation.

You're eating in a dining hall surrounded by other girls. You're living with roommates. You're hearing conversations about calories and workouts. You're seeing who goes to the gym and who doesn't. You're noticing what people order and what they leave on their plates.

And whether you realize it or not, you start using the women around you as a reference point.

You see your friend eating very little and think, Maybe I'm eating too much.

You see someone working out every day and think, Maybe I need to be doing more.

You hear someone say she hasn't eaten all day and somehow that becomes evidence that you're not as disciplined as she is.

But here's what I want you to understand:

You don't actually know what healthy looks like for her body just by watching her.

You don't know what her body requires to maintain its own energy balance. You don't know what she eats the rest of the day, what her menstrual cycle looks like, how much she's exercising outside of the hour you see her at the gym, or how her body is responding to all of it.

And even if you knew all of those things, her body would still be her body.

Not yours.

That girl who seems to eat less than you may genuinely need less food. Or she may not be eating enough either. She may have a completely regular cycle, or she may not have had one in months.

You simply can't look at another woman's plate and use it to determine what your body needs.

And yet, that's exactly what so many young women are doing.

Maybe you're not “restricting.” Maybe you're just not eating enough.

This is another piece that can be confusing.

A lot of the college women I work with don't think they're restricting food.

They're not living on lettuce.

They're not intentionally starving themselves.

They may actually eat a pretty nutritious diet.

Greek yogurt. Eggs. Oatmeal. Fruit. Chicken. Rice. Vegetables. Smoothies. Protein bars.

So when someone suggests that they aren't eating enough, they're genuinely confused.

But I eat healthy.

And I believe you.

The issue isn't necessarily that the food you're eating is “bad.”

The issue may be that your body needs more total energy than you're giving it.

This is an important distinction.

Your body doesn't just need vitamins, minerals, protein and vegetables. It needs enough overall energy to support everything you're asking it to do.

And if you're walking across campus all day, going to the gym six days a week, running, studying, dealing with the stress of college and not eating enough to match all of that, your body has to prioritize.

Functional hypothalamic amenorrhea is one possible consequence of low energy availability. The Endocrine Society's clinical guideline recommends addressing the underlying energy imbalance, which may involve increasing caloric intake, improving nutrition, decreasing exercise, or a combination of these. For some women, restoring energy balance may also require weight gain.

That's not because your body is broken.

It's because your body is adapting.

And then there's the gym.

Maybe you love it.

This is where I want to be really careful, because I don't want you to hear that exercise is bad.

Maybe the gym is actually one of the best parts of your day.

It's where you see your friends. It's where you feel strong. It's where you can turn your brain off for an hour.

Maybe when you're stressed about an exam, you go for a run.

When you're homesick, you go to the gym.

When you have a bad day, you work out.

When you're anxious, you move.

So when someone tells you that you need to exercise less, what you hear isn't simply, “Let's decrease your energy expenditure.”

You hear, “Take away the thing that helps me cope.”

I understand why that feels awful.

But sometimes something can be good for you and still be too much for your body right now.

Exercise is healthy.

More exercise isn't automatically healthier.

And if your body is consistently telling you that it isn't recovering, through a missing period, changes in performance, fatigue, poor sleep, or other signs, it's worth asking whether your current amount of movement is actually supporting you.

Sometimes recovery means finding other ways to manage stress for a while.

It might mean taking a walk instead of going for a run.

It might mean sitting outside.

Calling your mom.

Journaling.

Taking a nap.

Going to therapy.

Letting yourself have an afternoon where you don't accomplish anything.

And for a woman who has always used exercise as her way of managing stress, that last one can be surprisingly hard.

“But I'm disciplined.”

I hear this one a lot, too.

Maybe you've always been proud of your discipline.

You're the girl who gets her assignments done. You show up. You don't make excuses. You go to the gym even when you're tired. You stick to your goals.

And now period recovery is asking you to do something that feels completely opposite.

Eat more.

Rest more.

Stop trying to earn your food.

Let yourself miss a workout.

It can feel like you're being asked to become lazy.

But what if discipline isn't the thing you're missing?

What if you've simply become incredibly disciplined at doing something your body no longer needs you to do?

You can be disciplined and under-fueled.

You can be disciplined and have hypothalamic amenorrhea.

You can be disciplined and still need a snack.

Your body doesn't reward you for being able to tolerate the least amount of food or the most amount of exercise.

It responds to what it actually receives.

Let's talk about the rice cake.

I say this gently because there is nothing inherently wrong with a rice cake.

But if you've gotten to the point where a rice cake is what you believe you should eat for a snack because anything more feels excessive, that's worth paying attention to.

Maybe you have a rice cake with peanut butter.

Maybe you have two.

Maybe you add a banana.

Maybe you have a granola bar.

Maybe you realize you're actually hungry and make yourself something more substantial.

And maybe that feels incredibly uncomfortable at first.

That's okay.

Because period recovery often asks you to question things you never thought needed questioning.

You've been taught that a “good” snack is small.

That a meal should be mostly vegetables and lean protein.

That carbohydrates should be controlled.

That eating more means you've lost control.

That dessert is something you have to earn.

That exercise can make up for what you ate.

None of those rules are requirements for having a healthy relationship with food or a healthy menstrual cycle.

Your body needs energy.

Sometimes a lot more than you think.

“But I don't want to gain weight.”

Let's be honest.

This is often the part nobody wants to say out loud.

You may want your period back desperately.

You may understand the science.

You may even know that you're not eating enough.

And you may still be terrified of gaining weight.

I don't think that fear makes you shallow.

I think it makes you human.

Especially when you've spent your entire life receiving messages that smaller is better.

Smaller is healthier.

Smaller is more attractive.

Smaller means you're disciplined.

So when period recovery asks you to loosen your grip on controlling your body, it can feel like you're losing something.

Sometimes your body may need to change.

Sometimes it may not.

But I don't want you to make your entire recovery dependent on whether your body can return to a menstrual cycle without ever changing size.

The Endocrine Society specifically acknowledges that restoring energy balance in women with hypothalamic amenorrhea may require weight gain.

That doesn't mean every woman with a missing period needs to gain weight.

It means weight gain cannot automatically be treated as the worst possible outcome when your body is asking for more nourishment.

Your health is bigger than your clothing size.

And your period is not something you should have to starve yourself to keep.

Your period isn't only about getting pregnant someday.

I've had women tell me, “I don't care about fertility right now.”

And I understand.

If you're 18 and trying to survive organic chemistry, the last thing you're thinking about may be having a baby.

But your menstrual cycle isn't only important because you might want children someday.

Your reproductive hormones are connected to other aspects of your health, including bone health.

This matters particularly during your teens and twenties, when you're still building and maintaining bone mass.

The Female Athlete Triad literature has shown the relationship between low energy availability, menstrual dysfunction and bone health, and the broader RED-S framework recognizes that inadequate energy availability can affect multiple physiological systems—not simply your period.

So if your period disappears, I don't want you to shrug and say, “I'll worry about that when I'm ready to have kids.”

Your body is giving you information right now.

It's worth listening to.

And if you're the mom reading this...

Maybe you're reading this because your daughter went away to college and something changed.

She's exercising constantly.

She's become more particular about food.

She's lost her period.

She's telling you she's fine.

And you're not sure whether you're being dramatic or whether something really is going on.

I want to tell you that it's worth paying attention.

But I also know that telling an 18-year-old, “You need to eat more,” doesn't always work.

Especially if she's already afraid of gaining weight.

She may hear that as criticism.

She may feel like you're watching everything she eats.

She may pull away.

Sometimes the more useful conversation is simply helping her become curious about what's happening.

When was your last period?

How much are you exercising?

What happens emotionally when you have to miss a workout?

Do you feel like you're eating enough during the day?

Have you noticed changes in your energy, sleep or mood?

And perhaps most importantly:

What would it mean if your body actually needs something different than the girls around you?

Because that is often the real work.

Not convincing her that her friends are unhealthy.

Not convincing her that the gym is bad.

Not forcing her to eat.

It's helping her understand that her body gets to have its own needs.

Maybe your version of “healthy” needs to change.

This is the conversation I wish we were having with more young women.

You don't have to be the girl who eats the least.

You don't have to be the girl who works out the most.

You don't have to prove that you can skip a meal without being hungry.

You don't have to finish every workout.

You don't have to make your body smaller to prove that you're taking care of it.

And you don't have to copy what everyone around you is doing.

Maybe right now, being healthy looks different for you.

Maybe it means eating breakfast even though your friends don't.

Maybe it means adding an afternoon snack.

Maybe it means ordering the pasta.

Maybe it means taking Sunday off from the gym.

Maybe it means eating dessert without trying to compensate for it tomorrow.

Maybe it means allowing your body to change.

Maybe it means learning that you can still be ambitious, athletic, disciplined and successful without constantly pushing your body to its limits.

And maybe the hardest part is accepting that the healthiest choice for you might not look very “healthy” according to the rules you've been following.

That's okay.

You don't have to look like everyone else to be healthy.

If you're a college woman with a missing period, this is where I can help.

This is where so many women get stuck.

They've heard the advice:

Eat more. Exercise less. Reduce stress.

But then they're left sitting there thinking:

Okay... but what does that actually mean for me?

How much more food?

How much less exercise?

What if I'm already eating a lot?

What if I gain weight?

What if I can't imagine giving up the gym?

What if my friends think I'm being unhealthy?

What if I do everything “right” and my period still doesn't come back?

Those are the gray areas.

And honestly, those are the areas where period recovery gets really complicated.

Because you're not just changing your food.

You're changing your relationship with exercise, your body, your identity, your social environment and sometimes the definition of what you've always believed health was supposed to look like.

That's why I don't believe period recovery should be reduced to a generic list of foods to eat and workouts to stop.

You deserve to understand why your period disappeared and what your individual body needs to feel safe enough to bring it back.

If you're a college woman with a missing period, or you're a mom worried about your daughter's cycle, I help women navigate exactly this.

You don't have to figure out the gray areas alone.

You can apply for period recovery coaching here.

Your missing period isn't something to be embarrassed about.

And it isn't proof that you've failed.

It's information.

Your body is talking to you.

You just have to be willing to listen.

PS- the pill does not give you a real period !

The science behind hypothalamic amenorrhea and low energy availability

If you want to understand the research behind what I've talked about here, I recommend starting with the Endocrine Society's clinical practice guideline on functional hypothalamic amenorrhea. It outlines how clinicians evaluate FHA and emphasizes correcting the underlying energy imbalance, which may involve increasing energy intake, improving nutrition, reducing exercise, and sometimes restoring weight. Endocrine Society — Functional Hypothalamic Amenorrhea Guideline

The Female Athlete Triad Coalition's consensus statement is also an important resource because it explains the relationship between low energy availability, menstrual dysfunction and bone health. Female Athlete Triad Coalition Consensus Statement

And the International Olympic Committee's consensus work on Relative Energy Deficiency in Sport (RED-S) is helpful for understanding why inadequate energy availability can affect much more than menstruation, including bone, metabolic, immune and cardiovascular health and athletic performance. IOC Consensus Statement on RED-S

A missing period can have many causes, so it shouldn't automatically be assumed to be hypothalamic amenorrhea. Pregnancy, thyroid disorders, hyperprolactinemia, PCOS and other medical conditions may need to be considered and ruled out by an appropriate healthcare professional.
