Metformin – what is it?

Metformin is used to treat type 2 diabetic symptoms. The medication has been used as an off-label treatment for PCOS. It lowers blood sugar by normalizing insulin levels. Moreover, it also reduces blood sugar by reducing the absorption of sugar by the intestines and liver.

Metformin restores hormonal balance. Also, it treats metabolic abnormalities associated with insulin sensitivity. Besides, it helps lower LDL cholesterol and burns fat. 

If you are looking to shred some pounds, it is also a beneficial drug for losing weight.

Besides insulin resistance, Metformin also improves fertility and treats gestational diabetes.

Metformin As a Fertility Drug

Metformin is used to treat PCOS symptoms, but it is not prescribed for fertility. Then, how can Metformin help you to get pregnant if it isn’t a fertility drug?

It can help to improve fertilization by regulating hormones and induce ovulation. So, those who take it will have higher chances of conception than those who don’t.

Metformin suppresses the levels of estrogen, testosterone, and androgen that prevent ovulation. Also, it balances hormone levels by reducing insulin sensitivity. Thus, it results in a regulated menstrual cycle. In other words, it increases the possibility of getting pregnant.

Also, it is less likely to cause ovarian hyperstimulation syndrome (OHSS). Which is a condition in which the ovaries swell and leak fluid to release eggs.

However, Metformin alone cannot help you to get pregnant. To improve fertility, you must take other fertility medications along with metformin. Additionally, Vitamin B6 and other supplements can also help to maintain pregnancy.

Yet, you should consult a gynecologist before taking over-the-counter medicines with Metformin. Otherwise, you can experience severe side effects on your fertility and menstrual cycle.

A multitude of variables determines pregnancy time. They include:

  • Body mass index (BMI)
  • Age of females
  • The health of Fallopian Tubes

Also, nutrition and hormone levels have an impact on fertilization and implantation.

Unfortunately, infertility has one of the awful aspects; you can’t predict how long you’ll wait to get pregnant. But, It’s good news, though, that you can treat PCOS infertility.

Women who desire pregnancies with PCOS receive Metformin as their only medication. In general, Metformin takes effect in 3-21 days. So it is recommended to take it for 3 months or less (60 to 90 days) for conception.

Indeed, Metformin is usually prescribed to those who have trouble conceiving with PCOS. They will likely get pregnant any day now.

Additionally, a healthy diet, exercise, and safe sex are also part of metformin therapy. Still, if you’re having trouble getting pregnant, doctors might give you another fertility treatment.

When PCOS women take Metformin, they are more likely to become pregnant. During treatment, Metformin lowers insulin levels, which can help maintain a healthy weight; they will start ovulating independently (without medication). In turn, it increases the chance of getting pregnant.

Having regular ovulation, though, does not guarantee that you can become pregnant. Indeed, safe conception requires other factors as well.

How Much Metformin Should I Take to Get Pregnant?

Diabetes type 2 and PCOS are treated differently with Metformin. It depends on the patient’s medical history, insulin sensitivity, and immunity.

You should take 500 mg of it per day to get your body used to it. After one week, this dosage increases to 1000 mg per day, then to 2000 to 2500 mg per day.

However, when your body reacts to a high dose of 2000 or 2500 mg per day, you may be reversed back to 1000 mg per day. To be effective, you should take 500 mg Metformin three times a day along with a balanced diet.

Although Metformin is an effective drug to recover from PCOS and improves fertility, don’t take high dose of it. It would be best if you took it under the doctor’s guidance.
