What is period flu?

Have you ever felt flu symptoms on your period without actually having the flu? Well, guess what? You’re not the only one. 

In fact, a menstrual cycle flu is actually a relatively common experience. 

“Period Flu” is the common term associated with these particularly severe symptoms of PMS. But, it is not the usual flu or viral illness you’re thinking of. 

Rather, it describes the discomfort that comes with menstrual cycle illness, and gives you a warning sign to pay attention to your body.

If your pain during this hormonal flu during periods feels worse than a typical flu, it’s important to feel comfortable asking your doctor what steps to take to alleviate some or all of your symptoms. 

This blog post will take you through the symptoms of period flu, what it’s telling you about your body, and when you should seek medical attention. 

What are symptoms of period flu?

All bodies are different, and therefore, all menstrual flu symptoms may vary from person to person. 

As the “pre” in “premenstrual syndrome” suggests, you may experience premenstrual flu symptoms, along with PMS, up to two weeks before the first day of your period, and until the last day of your cycle. 

Some symptoms to look out for include: 

  • Nausea
  • Period Flu Headache
  • Dizziness
  • Muscle aches
  • Constipation
  • Diarrhea
  • Menstrual Flu Fatigue
  • Cramps
  • Bloating
  • Period Flu Body Aches
  • Abdominal pain
  • Fever or chills
  • Difficulty concentrating

Many individuals also feel symptoms that affect their emotions in addition to their bodies, such as increased depression or anxiety around their period, from not only PMS but also this flu-sick feeling.

What are some period flu causes?

Because flu-like symptoms during period are often reported after ovulation, it is assumed to be a result of fluctuating hormone levels. Post ovulation, progesterone levels rise and estrogen levels fall.  

Progesterone and prostaglandins

If you are feeling feverish or have that sick feeling, it is typically because your body is fighting off infection. Because prostaglandins are like messengers within your body and progesterone is like a warning signal in your uterus, they are used to destroy viruses or bacteria. 

Prostaglandins cause strong muscle contractions and cramps in your body, which cause all sorts of discomfort. 

Estrogen

Period flu and hormones are closely tied together. As estrogen levels dip rapidly, fatigue, cramps, and mood swings may shortly follow.

It also may impact your serotonin levels, a specific neurotransmitter. These chemical and therefore emotional imbalances amplify menstrual flu causes.
