What is an HSG test? HSG is short for Hysterosalpingography, and is an out-patient procedure where a dye is injected into the uterus via the cervix, to investigate whether the fallopian tubes are blocked.
It involves the use of an x-ray, for viewing the movement of the dye, and you would have a tube inserted through the cervix, so that the contrast fills the uterus.
The contrast moves into the fallopian tubes, and the radiologist can view whether it moves out of the tubes, or gets stuck somewhere within the fallopian tubes.
The HSG test provides the doctor with a clear way of viewing the structure of the uterus and fallopian tubes, and can be used to determine whether scars, adhesions, or tumors are blocking the fallopian tubes.
It can also confirm whether the uterus is free of structural abnormalities.
Even though the HSG is an out-patient diagnostic test, it carries a certain amount of risk.
The most common risk is infection from the test.
Some doctors may prescribe medication to mitigate that risk, so it's worth enquiring about this before having your test.
Additionally, you may have a reaction to any of the chemicals used in the test.
This can lead to severe inflammation, and inflammation can lead to adhesions, which may worsen your fallopian tubes.
It is important to make sure the chemicals are compatible with your body before the test.
You can usually return to work a day after the test, but you may experience cramps for a few days after the test.
Some women report feeling faint, or bleeding as a result of the HSG.
While these side effects are common, it is worth calling your doctor just in case they develop into something worse.
You must not perform an HSG test if you think you might be pregnant.
You should also steer clear of the test if you have Pelvic Inflammatory Disease, or any abnormal vaginal bleeding.
It is extremely rare that the test can damage your fallopian tubes, but forewarned is forearmed.
