What Your Period Can Tell You About Your Health

What your period can tell you about your health

Periods are often talked about only as a problem: cramps, stains and bad moods. But your period is also a useful signal. For most girls and women, a regular cycle is one sign that the body's hormones are working as they should. A change in your period can be an early hint that something needs a doctor's attention.

This post explains what your period can tell you, what it cannot, and when to get help.

A regular cycle is a good sign

A period comes when hormones from the brain and the ovaries rise and fall in the right order. When this happens on a fairly steady rhythm, it usually means these hormones are in balance.

Count your cycle from the first day of one period to the first day of the next. For adults, a cycle of 21 to 35 days is normal. In the first few years after periods start, cycles are often longer and less regular. That is usually fine.

Changes are worth noticing

A young woman smiles in a mirror as she ties her hair.

Your period can change for ordinary reasons, such as stress, illness, travel or a change in weight. It can also change because of a health condition. Some common ones are:

  • Thyroid problems. An underactive or overactive thyroid can make periods heavier, lighter or irregular.
  • PCOS (polycystic ovary syndrome). A hormonal condition that often causes irregular or missed periods, acne and extra hair on the face or body.
  • Anaemia. This works the other way round: heavy periods can lower your iron and leave you tired, breathless or dizzy.
  • Fibroids or polyps. Growths in the womb that can cause heavy or long periods.
  • Very low body weight. Not eating enough, or very hard exercise, can make periods stop.

Your period cannot tell you which of these you have. It is a reason to see a doctor, who can check.

A late or missed period

If you have had sex, a late or missed period can mean you are pregnant. A home pregnancy test is the quickest way to find out. Some people have light bleeding in early pregnancy, so a light period does not prove you are not pregnant.

If your periods stop for three months and you are not pregnant, see a doctor.

Feeling better once bleeding starts

Many girls and women feel bloated, sore or low in the days before a period. For most, this eases once bleeding begins. Noting how you feel through the month helps you plan ahead. It also helps a doctor if the symptoms are severe.

What a period does not do

You may have heard that periods clean the body of toxins, or that period blood is dirty. Neither is true. Period blood is the lining of the womb, with some blood and mucus. The body clears waste through the kidneys, liver and gut, not through periods. A period is a normal part of how the body works. There is nothing impure or shameful about it.

Periods also do not make you live longer, lower your blood pressure or make you more beautiful. Losing blood each month can lower your iron, so iron-rich food matters: dals, rajma, chana, ragi and green leafy vegetables, and eggs, fish or meat if you eat them. A squeeze of lemon or some amla with the meal helps the body absorb the iron.

When to see a doctor

  • Your cycle is often shorter than 21 days or longer than 35 days.
  • Your period lasts more than seven days.
  • You soak through a pad every hour or two, or pass large clots.
  • Your periods stop for three months and you are not pregnant.
  • You bleed between periods, after sex, or after menopause.
  • Pain keeps you away from school, college or work.
  • Your periods have not started by the age of 15.

FAQs

Is a regular period a sign of good health?

Often, yes. A steady cycle usually means your hormones are working well. It does not rule out every health problem, so see a doctor if you have other symptoms.

Do periods remove toxins from the body?

No. Period blood is the lining of the womb. It is not dirty, and it does not carry toxins out of the body.

Can irregular periods mean something is wrong?

Sometimes. Stress, illness and weight change can all affect your cycle, and so can thyroid problems and PCOS. If your periods stay irregular for several months, see a doctor.

Does a period mean I am not pregnant?

Usually, but not always. Some people have light bleeding in early pregnancy. If you have had sex and your period is late or unusually light, take a pregnancy test.

In short

Your period is a normal part of life for most girls and women. It is not a cure-all, and it is not a curse. Noticing it, and seeing a doctor when something changes, is one of the simplest ways to look after your health.
