Oral contraceptives are the preferred form of contraception for many men and women, as they are safe and effective in avoiding unwanted pregnancies. However, there are contraindications to taking birth control pills, and not everyone can take oral contraceptives. So who can't take oral contraceptives? How are oral contraceptives used?

Ten types of people cannot take oral contraceptives

In general, contraceptives can be used by married women of childbearing age who are in good health, but oral contraceptives should not be used by women in the following situations:

1. Women with acute and chronic hepatitis and nephritis should not take it. Because the contraceptive pills that enter the body are metabolized in the liver and excreted by the kidneys, if women with acute and chronic hepatitis and nephritis use it, it will increase the burden on the liver and kidneys.

2. People with heart disease or poor heart function cannot use it. The estrogen in birth control pills can retain water, sodium and other substances in the body, which will increase the burden on the heart.

3. Women with high blood pressure should not use it. A small number of women take the drug to increase their blood pressure.

4. People with diabetes and family history of diabetes should not use it. Taking birth control pills can cause a slight increase in blood sugar, making occult diabetes become overt, so it can have adverse effects on women with diabetes.

5. Women with hyperthyroidism should not use contraceptives until they are cured.

6. Patients with benign breast tumors, uterine fibroids and various malignant tumors should not use it to avoid adverse effects on tumors.

7. Those who have suffered from vascular embolic diseases (such as cerebral thrombosis, myocardial infarction, vasculitis, etc.) in the past or present cannot use it. The estrogen in birth control pills may increase blood clotting and can aggravate cardiovascular disease.

8. Women suffering from chronic headaches, especially migraine and vascular headaches, should not use it, otherwise it will aggravate the symptoms.

9. If you have low menstrual bleeding in the past, it is best not to use it. Long-term use of birth control pills can cause the endometrium to shrink and reduce menstrual flow.

10. Lactating women should not use it. Birth control pills can reduce milk production and reduce the quality of milk, and can also enter the milk and have adverse effects on nursing babies, so breastfeeding women should not use them.
