Abnormal vaginal bleeding is a very common condition that can occur at various ages, depending on the underlying cause and severity of the disease. Generally, people often assume that any bleeding from the vagina is always menstrual blood.
In reality, normal menstruation is blood flowing from the uterine cavity, consisting of blood and small tissue fragments shed in cycles according to hormonal changes in the body. The interval of a cycle usually ranges between 21 - 35 days, but on average, menstruation occurs every 28 days (or plus no more than 7 days), with an estimated blood volume of about 30 – 40 cc per cycle.
If you experience vaginal bleeding that does not match the characteristics of normal menstruation mentioned above, you should promptly consult a specialist obstetrician-gynecologist to identify the cause and receive treatment in the early stages of the condition.
Doctors can simply classify the causes into 2 types based on the location of the bleeding:
Most patients experience bleeding from causes inside the uterine cavity combined with other underlying conditions that affect it, such as blood disorders, liver disease, kidney disease, thyroid disease, etc. The attending physician will provide appropriate diagnostic recommendations tailored to each individual.


In addition, the doctor may recommend additional investigations, such as blood tests to check hormone levels, ultrasound examination, dilation and curettage (D&C) to test tissue from the uterine cavity, or hysteroscopy/laparoscopy.

If you experience vaginal bleeding that does not match normal menstrual patterns, you should consult a doctor promptly to identify the cause and receive treatment.
