Is the HSG Test Painful? What You Need to Know

A hysterosalpingogram (HSG) is an X-ray procedure that visualizes the uterus and fallopian tubes. Many individuals scheduled for an HSG test are concerned about potential pain.

Understanding the HSG Procedure

The HSG procedure begins with a medical professional placing a speculum into the vagina to visualize the cervix, similar to a routine gynecological exam. The cervix is cleaned, and a thin catheter is inserted into the uterus. This catheter introduces a contrast dye.

Once the catheter is in place, the dye is slowly injected into the uterine cavity. As the dye fills the uterus, it outlines its shape and flows into the fallopian tubes. X-ray images are captured in real-time using fluoroscopy, allowing the medical team to observe the dye’s path. If the fallopian tubes are open, the dye passes through them and spills into the pelvic cavity. This process evaluates the patency of the fallopian tubes and identifies structural abnormalities within the uterus. The procedure takes less than 5 minutes, though the total appointment time is longer.

Addressing the Pain Question

Pain during an HSG test can vary among individuals. Many describe the sensation as similar to menstrual cramps, ranging from mild discomfort to moderate or even intense cramping. This cramping sensation arises as the contrast dye fills and slightly distends the uterus, causing the uterine muscles to contract. The discomfort is generally brief, often peaking during the dye injection and subsiding shortly after the procedure concludes.

Several factors can influence the level of pain experienced:
Individual pain tolerance.
The presence of blocked fallopian tubes, as increased pressure may occur when the dye encounters an obstruction.
Pre-existing conditions such as endometriosis, pelvic inflammatory disease (PID), or uterine fibroids, which can make the uterus and surrounding tissues more sensitive.
Anxiety or nervousness before and during the procedure.

Coping with Discomfort During an HSG

Preparing for an HSG can help manage potential discomfort. Taking over-the-counter pain medication, such as ibuprofen, about 30 to 60 minutes before the procedure is commonly recommended to help reduce cramping. Some clinics may also prescribe antibiotics to prevent infection, especially if there’s a history of tubal issues. It is advisable to discuss any concerns or anxieties with the medical team beforehand, as open communication can lead to a more comfortable experience.

During the HSG, practicing relaxation techniques like deep, steady breathing can help relax pelvic muscles and alleviate tension. Focusing on distraction, such as listening to music or engaging in conversation, may also help divert attention from any discomfort. Patients should feel empowered to communicate with the medical professional performing the test if the discomfort becomes too intense.

After the procedure, mild cramping or light spotting is common for a day or two. It is generally recommended to use sanitary pads instead of tampons and to avoid intercourse for a day or two to minimize infection risk. Persistent or worsening pain, fever, or foul-smelling discharge should prompt immediate contact with a healthcare provider.

Why the HSG Test is Performed

The HSG test is primarily used in evaluating fertility concerns. Its main purpose is to determine if the fallopian tubes are open, which is essential for conception as sperm travel through these tubes to reach the egg. Blocked fallopian tubes are a significant cause of infertility, and the HSG can pinpoint such obstructions.

Beyond tubal patency, the HSG also assesses the shape and structure of the uterine cavity. This allows for the detection of abnormalities that could interfere with pregnancy, such as:
An irregularly shaped uterus.
Polyps.
Fibroids.
Scar tissue (adhesions).

While the test is mainly diagnostic, there is some evidence to suggest that the flushing action of the dye can sometimes clear minor blockages, potentially increasing the chance of natural conception in the months following the procedure.
