Does Drinking Alcohol Affect Your Menstrual Cycle?

Have you ever wondered, “why does my period stop when I drink?” If you have, you aren’t alone.

Alcohol and period problems are a common duo. Any person can attest to the fact that alcohol impacts your body in more ways than one. From reduced inhibitions to a hangover that will make you regret your decision to drink, alcohol can have a huge impact on your mind and body, including your menstrual cycle. However, there’s a lot of conflicting research on “does drinking alcohol affect your menstrual cycle,” so let’s dive into it.

What Is a Menstrual Cycle (Period)?

Menstruation is the monthly shedding of the lining of a woman’s uterus (which you may know as “the womb”). During a normal period, the lining of the uterus sheds, preparing it for a possible pregnancy. Menstrual blood flows from the uterus through the cervix and out of the body through the vagina.

Also referred to as a menstruation cycle or period, a menstrual cycle refers to the sequences of events that occur within a woman’s body as she prepares for a possible pregnancy. A menstrual cycle begins on the first day of the woman’s period, which typically lasts anywhere from 4 to 7 days. The time between cycles, or periods of menstrual bleeding, can range from 28 to 35 days.

How It Works

The steps in a menstrual cycle are triggered by the fluctuation of hormones. A gland in the brain called the pituitary gland and the ovaries in the female reproductive tract work together to release certain hormones at a certain time during your period.

The menses phase is the first phase of a menstrual cycle, during which the uterus will shed, and usually, the woman will bleed for 2 to 7 days. The follicular phase is next, which commonly lasts 6 to 14 days.

During this phase, the level of the hormone estrogen rises, causing the lining of the uterus to grow and thicken again. Another hormone called the follicle-stimulating hormone is also released during this phase, causing follicles in the ovaries to grow to form a fully mature egg.

Then, ovulation happens, which occurs roughly at day 14 in the 28-day menstrual cycle. During this phase, the luteinizing hormone causes the ovaries to release their eggs, otherwise known as ovulation. The last phase of a period is the luteal phase, in which the egg that was released from the ovary travels through the fallopian tubes to the uterus.

The level of the hormone progesterone rises, preparing the uterus lining for pregnancy. If the egg is fertilized by sperm, then it attaches itself to the lining of the uterus, forming a pregnancy. If not, then the levels of estrogen and progesterone drop, and the linking of the uterus is once again shed during the menstrual period.

Can Alcohol Affect Your Period?

Yes, alcohol can affect your menstrual cycle (period). Stopped or irregular menstrual bleeding after drinking alcohol is a common concern for many women. But why does this happen?

Hormonal Imbalance

Alcohol can stop or cause irregular menstrual cycles because it increases levels of hormones like estrogen and testosterone, and sometimes the luteinizing hormone. This causes a hormonal imbalance, which in turn can affect whether your period occurs, how long it lasts, and how heavy it is.

Drinking alcohol can also increase androgen levels during the follicular phase and estrogen in the ovulation phase. This effect showed to be most apparent in women who engaged in binge drinking. Drinking alcohol during your period can also worsen common menstrual symptoms, including moodiness, trouble sleeping, bloating, and cramps.

Worsening Cramps

Not only does drinking alcohol affect your menstrual cycle by causing bloating, but it can also worsen cramps by impacting the balance of prostaglandins. Prostaglandins are a group of lipids made at sites of tissue damage or infection to help heal injuries and illness. They control processes like inflammation, blood flow, formation of blood clots, and they even help to induce labor.

During a menstrual cycle, prostaglandins trigger contractions in the uterine muscle. Higher levels of prostaglandins cause more severe menstrual cramps. Alcohol increases prostaglandins levels, worsening your period cramps.


Alcohol is notorious for dehydrating people, especially when it’s heavily consumed and the only thing the person has had to drink. As a result, drinking heavily can worsen period cramps by thickening menstrual fluids and blood, making it more difficult for them to pass through the uterus, through the cervix, and out of the body.

Heavier Period

Alcohol can also make your period heavier or cause you to bleed more during menstruation. Since alcohol is both a blood thinner and because it increases estrogen levels, heavy drinking may lead to a heavier period. That’s because estrogen stimulates the growth of endometrial tissue or the lining of the uterus that’s being shed. This means that you’ll have more to shed during a period, which means heavier bleeding.

The Takeaway

Keep in mind that alcohol’s effect on period cycles depends on how often and how much of it you drink. While one alcoholic drink every once in a while won’t affect your period (unless you have a particular condition), heavy drinking definitely will. Even if you consider yourself to be a social drinker, the line between casual drinking and binging can blur if you aren’t careful.

Women who are addicted to alcohol or unable to control their drinking increase their risk of stopped or irregular periods.
