Gymnast PMS and Painful Periods: What Actually Helps

Gymnast PMS can be brutal. Cramps that keep her curled up on the couch, bloating in a leotard, mood swings that seem to come out of nowhere and a period that wipes her out right before a meet. A lot of families are told this is just “part of being a girl” or “part of being a gymnast.” Here’s the thing: it’s COMMON, but that doesn’t make it normal.

Let’s talk about what PMS and painful periods actually are, why gymnasts get hit so hard, what really helps (food first), where birth control fits and when it’s time to talk to her doctor.

First: is she getting a period at all?

Before we talk about PMS, we need to know she’s getting a period, and getting it on time. Her period is often called the fifth vital sign, because it tells us whether her body has enough energy to grow, build bone and run its hormones.

• No period by 15 is a red flag, not “normal for a gymnast”
• Losing her period for 3+ months after it started is a red flag
• No breast development by 13 is worth a conversation with her doctor

If any of those sound familiar, start with Do Gymnasts Get Periods? and our guide to REDs in gymnasts. Late and missing periods are almost always an underfueling story, and that needs to be addressed first.

What is PMS?

Her menstrual cycle has two halves. The first half starts with her period and runs until ovulation, around day 12-14 of a typical 28-day cycle (anywhere from 21 to 35 days can be normal). The second half, called the luteal phase, runs from ovulation until her next period. PMS (premenstrual syndrome) shows up in that second half, usually in the 1-2 weeks before her period, and fades once her period starts.

It used to be blamed only on estrogen and progesterone. We now know brain chemicals that control mood, like serotonin, are part of it too.

Common PMS symptoms include:

• Physical: bloating, cramps, breast tenderness, headaches, extreme fatigue
• Mood and behavior: irritability, mood swings, anxiety, feeling down, food cravings, feeling extra sensitive

Painful periods (the medical term is dysmenorrhea) are a little different: that’s cramping and pain during the period itself. Many gymnasts deal with both.

Are gymnasts more likely to have PMS?

Possibly. In a study of girls and young women ages 16-22, PMS was more common in competitive athletes than non-athletes (49% vs. 32%), and it went up with longer, more intense sports careers. Athletes are also very in tune with their bodies, so they may simply notice symptoms more. Either way, if PMS is getting in the way of her training, school or life, it deserves attention.

What causes PMS and painful periods in gymnasts?

There isn’t one cause. But in our practice, the same patterns show up again and again in gymnasts with rough periods.

Underfueling

Her hormones need energy. When a gymnast doesn’t eat enough to cover 20+ hours of training plus growth, her body starts cutting corners, and hormones are one of the first places it cuts. That doesn’t always mean her period disappears. In a controlled study, women who ran an energy deficit started having subtle cycle problems, like not ovulating or a shortened second half of the cycle, and the bigger the deficit, the more often it happened. She can still be getting a period and still be underfueled.

The good news? It works the other way too. In the REFUEL study, exercising women with missing or irregular periods who ate only about 330 more calories a day (basically one more snack) were almost twice as likely to get their periods back.

Low carbs

So many gymnasts eat “so healthy” (lots of protein and veggies) but not nearly enough carbs for long bars and beam practices. Low carbs add stress to her system and leave her running on empty.

Long practices with little fuel

A 4-5 hour practice on one granola bar, long gaps between meals and not enough after practice. Even if her total food for the day looks OK, poor timing can leave her underfueled for hours at a time.

Minerals and iron

Minerals play a huge role in making and regulating hormones. Your uterus is a muscle, and when minerals are out of balance, the body struggles to calm inflammation, relax that muscle and use progesterone and estrogen the way it should. Gymnasts with heavy periods are also at higher risk for low iron, which makes fatigue even worse.

Stress, sleep and recovery

High training loads, school, competition nerves and not enough sleep all keep her nervous system stuck in fight or flight. Many of the gymnasts who come to us with awful periods are type A perfectionists who are completely depleted, stressed out and burnt out.

What about really heavy periods?

Heaviness is subjective, but there’s a big difference between changing a pad or tampon every few hours and soaking through a super plus in an hour. One reason we see really heavy periods with big clots: when she isn’t eating enough to support a full cycle, she may not ovulate. Hormones drop before the cycle finishes, the uterine lining keeps building, and when her period finally comes (sometimes 45-60+ days apart), it’s heavy.

What we see clinically

After working with hundreds (honestly, thousands) of competitive gymnasts, we’ve seen a clear pattern. Painful periods are rarely a standalone hormone problem. They’re usually the result of years of underfueling and mineral depletion, layered on top of high training stress and the needs of growth and development. Period pain is one of the first things to show up when her body doesn’t feel safe.

And here’s what almost no one asks at the doctor’s office: Is she eating enough? Is she mineral depleted? Is she actually ovulating? What’s going on with her nervous system?

Start with the big rocks

Before we talk about any specific foods or supplements, these need to be in place. If any of them are missing, no fancy PMS strategy is going to work.

1. Enough food, every day. This is the recovery gap: the difference between what her body NEEDS and what she’s actually getting. Closing it each and every day matters more than anything else on this list.
2. Enough sleep. (See Is Your Gymnast Getting Enough Sleep?)
3. Stress support. A therapist or sports psychologist can be HUGE for a high-level gymnast. Don’t be afraid to add them to her team.
4. Recovery, which depends on the first three.

Foods that help with PMS (food first)

We always take a food-first approach. Whole foods come with so much more than one vitamin or mineral, and every one of these foods already belongs in a gymnast’s diet for health and performance anyway.

Calcium

Calcium has some of the best research for PMS. In a large randomized trial, women who got 1,200 mg of calcium a day had their PMS symptoms drop by 48%, compared with 30% on a placebo, with improvements in mood, bloating, cravings and pain.

Teens need about 1,300 mg of calcium a day. That’s roughly 4-5 servings of dairy or fortified milk alternatives. Most gymnasts we see aren’t hitting that. Check labels on plant-based milks and yogurts, because many have much less calcium than dairy.

Calcium-rich foods: milk, yogurt, cheese, calcium-fortified milk alternatives, dark leafy greens, beans, canned salmon and sardines

Vitamin D

Vitamin D goes hand in hand with calcium for bone health, and low levels are common in indoor athletes. A high-level gymnast should have her vitamin D checked at least once a year. Test, don’t guess.

Vitamin D foods: salmon, trout, tuna, eggs, mushrooms and fortified foods

Iron

Iron carries oxygen in her blood and helps make serotonin, one of the “feel good” brain chemicals. In a 10-year study, women who ate the most plant-based (non-heme) iron had about a third lower risk of developing PMS. That kind of study can’t prove cause and effect, and taking extra iron “for PMS” isn’t helpful (too much iron isn’t good either). But iron-rich foods every day and yearly labs are something I recommend for every gymnast, especially once her period starts.

Iron-rich foods: beef, lamb, dark meat chicken and turkey, beans and lentils, spinach, egg yolks, raisins and fortified cereals

Magnesium

Magnesium helps with muscle function, nerve function, blood sugar and bone. Many athletes run low. Small studies suggest it may help with bloating and water retention, but the research is limited.

Magnesium-rich foods: dark leafy greens, nuts, seeds, beans, whole grains, avocado, fish and dairy

B vitamins

B vitamins help turn food into energy. Vitamin B6 helps make serotonin and dopamine, which affect mood. The research here is weaker, but higher intakes of B vitamins from FOOD (not supplements) have been linked to fewer PMS symptoms.

B vitamin foods: meat, poultry, fish, eggs, dairy, whole grains, fortified cereals, beans, bananas, potatoes and peanuts

What about mineral testing?

Step one is ALWAYS getting enough food in. But the most effective thing we’ve added for painful periods and bad PMS is mineral testing: HTMA (hair tissue mineral analysis) alongside her labs. We often see the same pattern in these gymnasts: low calcium, magnesium that’s out of balance, and zinc and copper that are off, all of which can affect estrogen, progesterone, inflammation and mood. Iron is a big one too. It’s not just about her ferritin, but whether iron can actually get where it needs to go.

When we correct those patterns while she’s fueling enough, that’s where we see the biggest improvements. Mineral support only works on top of enough food, never instead of it.

Foods to cut for PMS? Not so fast

If you search for PMS tips, you’ll find lists of foods to cut: salt, sugar, caffeine. Be careful with blanket advice like this for a gymnast who may already be micromanaging her food.

• Salt: cutting salt before her period can hurt her hydration and training, especially if she wasn’t eating a lot of it to begin with. She sweats a LOT at practice.
• Sugar: all carbs break down into sugar (glucose), which is her main fuel. Most gymnasts aren’t eating enough sugar to blame for their symptoms. More often, it’s over-restricting sugar that causes the struggle, not the other way around.
• Caffeine: the American Academy of Pediatrics recommends minimal caffeine for kids and teens. My bigger concern is that it masks fatigue and wrecks sleep. Energy should come from food. For older gymnasts who use caffeine, cutting it cold turkey right before her period can cause rebound headaches, so taper slowly instead.

Fueling around her period

Many gymnasts feel hungrier in the week before their period. That’s real. Her body is working a little harder in that second half of the cycle. This is NOT the week to cut back. A few simple things help:

• Keep her regular meals and snacks, and add more if she’s hungrier
• Keep carbs coming before and during practice, especially when she’s tired
• Lean on calcium- and iron-rich foods every day, not just that week
• Keep up fluids and electrolytes, especially if she’s bloated (cutting water doesn’t help bloating)

Birth control for gymnast PMS: is it the answer?

Birth control is often prescribed to gymnasts for painful periods, heavy periods or bad PMS. There can be a time and place for it, and that’s a decision for her and her doctor. But there are a few things every parent should know first.

• It’s not a real period. On most birth control pills, the monthly bleed is a withdrawal bleed when the hormone pills stop, not a period from ovulation. That means it can’t tell you whether she’s fueled enough anymore.
• It shuts down her own hormones. Birth control sends steady outside hormones that tell her ovaries to stop doing their job. Without ovulation, she doesn’t make her own progesterone, which is calming, anti-inflammatory and protective for her bones.
• It doesn’t fix the root cause. It quiets symptoms, but whatever her periods were like before birth control is usually what they’re like after. If underfueling, stress or low minerals are driving the problem, those are still there.
• It can deplete nutrients. Birth control can lower zinc, magnesium and B vitamins, which are tied to hormone production and stress resilience.
• It doesn’t fix a missing period. If she wasn’t getting her period because of underfueling, birth control just hides it.
• It doesn’t protect her bones the way her own hormones do. It’s often marketed to athletes as “bone protection,” especially after a stress fracture. The 2023 IOC consensus on REDs is clear that birth control isn’t a treatment for underfueling-related bone loss.

We’re not anti-birth control. If she’s sexually active, birth control has an important job, and that’s a conversation for her and her doctor. But for a young gymnast, it shouldn’t be the first or only answer for painful periods. If it’s being suggested, ask: Have we looked at her fueling, her labs and her stress first?

And if she’s already on it and wants to come off, don’t stop cold turkey. We fix her fueling, check labs and minerals and get support in place first, then she weans off with her doctor, so her symptoms don’t come roaring back before nutrition has time to work.

When to talk to her doctor

Talk to her pediatrician or gynecologist if she has:

• Period pain that makes her miss school or practice, or doesn’t get better with over-the-counter pain relief
• Very heavy periods (soaking a pad or tampon every 1-2 hours) or periods lasting longer than 7 days
• Periods that stop for 3+ months, or no period by 15
• Very irregular cycles, acne or extra hair growth, which can point to PCOS (polycystic ovary syndrome)
• Mood symptoms that are severe enough to affect friendships, school or how she feels about herself

PCOS deserves a quick note: in athletes, it’s often confused with missing periods from underfueling (hypothalamic amenorrhea), and the two can overlap. A good team looks at both.

Real gymnasts, real results

Every gymnast we’ve worked with who came to us with awful periods has been able to avoid birth control or come off it. A few of their stories (shared without names):

The gymnast who ended up in the ER

She got her period at a normal age, around 13. By 14 or 15, her PMS had become brutal: nausea, vomiting and stomach pain so bad that she ended up in the ER at a college camp, where they thought it was appendicitis. It was the start of her period. Her mom had already spent hundreds of dollars on supplements, and we had tried everything the research suggests (omega-3s, turmeric and more) without relief.

So we ran HTMA. Her results looked like so many of our gymnasts with these symptoms, with a copper imbalance that can affect estrogen and progesterone. We started minerals slowly (her body wasn’t ready for big doses right away), and within about 2-3 months her symptoms were all but resolved.

The Level 10 who bled every 2-3 weeks

A 15-year-old Level 10 got her period around 13 and a half or 14, and for over a year she bled every 2-3 weeks. Some irregularity in the first year is normal while her body is still figuring out ovulation, so her pediatrician kept saying to give it time. A year later, she and her mom were beside themselves, and they’d booked an appointment with an adolescent gynecologist at a well-known children’s hospital.

We started minerals in October. By December, she had normal cycles: about 5 days long and 28-35 days apart. By the time of her gynecologist appointment, her periods were normal. The gynecologist’s words? “Whatever you’re doing, keep doing it.”

The college gymnast who was always sick

Another gymnast had been on birth control since her sophomore year of high school because of her periods. Her freshman year in college, she was sick all season with every cold and flu going around, couldn’t train consistently and couldn’t make lineups. She wanted to know her body could have normal periods on its own. We did labs and HTMA, built a mineral plan and supported her off birth control. Within a few months, she had normal, manageable periods (no more changing her tampon all day), and she stayed healthy through cold and flu season.
