Question: Hi,

My wife has an issue since her teenage. She has irregular period. Sometimes, it takes 2-4 months for a period to happen. She then needs to take progestin medication like 'Norethisterone'. Period used to have heavy bleeding before, since last one year, this has stopped. Although, the period is still not regular. Please advise any suggestive diagnostics to find out the root cause of the issue.

Brief Answer:

Details below.

Detailed Answer:


Treatment for irregular periods during puberty and around the menopause is not usually necessary, but if irregular periods occur during the reproductive years, medical advice may be necessary.

The main cause of irregular periods are-

Thyroid Disorder (over-or underactive thyroids can cause a hormonal imbalance which can suppress your ovulation):

STD (Sexually Transmitted Disease)
Pregnancy (Irregular periods can sometimes be a sign of pregnancy. If you think you could be pregnant, see your doctor for a consult.)
Polycystic Ovary Syndrome (PCOS).

Diagnosis of the root cause of the issue is very difficult, this can be made by several blood test and Ultrasound and by treating gynaecologist.

It’s important she has a balanced and healthy diet all month. There are some particular foods that are very helpful in regulating periods and getting her menstrual flow going:

Pineapples and papaya are well-known home remedies for irregular periods. The bromelain in the pineapple and papaya will help soften and break down her uterus lining, which can help solve a period block.

Also, aim for an intake of half a teaspoon of cinnamon (mixed in warm lemon water with honey or in a glass of (almond) milk).

Some studies show that cinnamon helps regulate the insulin levels, which in turn can help regulate ovulation and therefore also having a regular menstrual cycle.

Hope I have answered your query. Let me know if I can assist you further.

Can you please advise the blood test to detect 'Polycystic Ovary Syndrome'? She doesn't have the other options, but most likely she has a hormonal issue. She is not pregnant.

Brief Answer:

Needs hormonal tests and ultrasound scan.

Detailed Answer:


Diagnosis of PCOD is done by ultrasound, transvaginal, transabdominal or 3D and there should be at least 10-12 follicles 2-10 mm in diameter or increased ovarian volume.

This is called 'pearl string appearance'. Investigations which are done to diagnose PCOD are FSH, LH, Prolactin, DHEA's etc under doctor's guidance.

Hope I have answered your query.

Take care
