Generally speaking, all healthy married women of childbearing age can use the pill, but women in the following situations should not use oral contraceptives: 1, women with acute and chronic hepatitis and nephritis should not take. Because the contraceptive pills into the body are metabolized in the liver and excreted by the kidneys, if women with acute and chronic hepatitis and nephritis use, will increase the burden on the liver and kidneys. 2.

The estrogen in birth control pills can make the body retain water, sodium and other substances, which will increase the burden on the heart. 3. Women with high blood pressure should not use it. A small number of women will have higher blood pressure after using the drug. 4, people with diabetes and family history of diabetes should not be used.
