Causes of Dizziness During Your Period

Do you sometimes experience dizziness and wonder what might be causing it? If you are menstruating, the reason you feel dizzy may be related to your menstrual cycle.

Dizziness is a sensation that often makes people feel off balance like the room is spinning. You may notice these symptoms more intensely when getting up quickly from sitting or lying down and you may lose your balance.

Dizziness From Menstrual Blood Loss

One of the most common causes of dizziness in menstruating girls and women is iron-deficiency anemia. If you have an average menstrual flow, you lose about 30 milliliters (mL) or roughly about 2 tablespoons of blood every month.

Usually, that is not enough blood loss to cause symptoms unless you already have an underlying condition causing you to be anemic. On the other hand, if you have really heavy periods month after month, it is possible for you to become anemic just from your menstrual blood loss.

Blood loss, whether it is chronic or acute, can result in iron deficiency anemia. When you bleed you lose red blood cells (RBCs). Your RBCs are the cells in your body that carry oxygen.

Your brain is very sensitive to even the smallest changes in oxygen concentrations in your blood. When your brain senses this relative lack of oxygen, you likely will become dizzy.

When you are anemic, increases in your activity that take blood flow away from your brain and into your muscles will cause you to be dizzy. In a way, this is an alarm by the brain to get you to stop what you are doing so it will get more oxygen.

In non-menstruating women and men, blood loss from an ulcer or another digestive system source can lead to anemia.

More Causes of Dizziness

Dizziness is also a symptom of several other diseases and conditions. These include balance disorders, ear problems, stroke, motion sickness, a sudden drop in blood pressure, or dehydration.

Dizziness is also a possible side effect of many different types of over-the-counter and prescription drugs. These drugs include medications for high blood pressure, asthma, and other breathing problems, heart diseases, pain, sedatives, and drugs used to treat ADHD and other mental health conditions.

Talk to your doctor right away if you suspect that a drug is causing dizziness. Never suddenly stop taking any drug without your doctor's approval.

When to See Your Doctor

Fortunately, most instances of dizziness resolve themselves without medical intervention. However, if you experience dizziness often, contact your doctor for diagnosis and treatment.

Your doctor will be able to assess what could be causing the symptoms, screen for any developing conditions, and provide any needed treatment.
