Why Does Sex Make Your Stomach Hurt?

Experiencing stomach pain during or after sexual activity can be a confusing and unsettling symptom. While common, this discomfort can range from a mild ache to more intense pain. Understanding its potential origins is important for addressing it appropriately. This article explores various reasons for abdominal discomfort during or after sex, from everyday physiological responses to underlying medical conditions.

Everyday Reasons for Discomfort

Stomach discomfort during or after sex often stems from common physiological reactions and mechanical factors. During sexual arousal and orgasm, the body undergoes muscle contractions throughout the pelvic region, including the uterus and surrounding abdominal muscles. These contractions, particularly during orgasm, can feel like cramping or a dull ache in the lower abdomen, similar to mild menstrual cramps. This is a normal and temporary response.

Digestive factors also frequently contribute to abdominal sensations. Gas and bloating, common digestive occurrences, can be exacerbated by certain sexual positions that apply pressure to the abdomen. This pressure can cause trapped gas to shift, leading to temporary discomfort or sharp pains. Changing positions or ensuring a comfortable digestive state before intimacy may help.

Deep penetration during intercourse can exert pressure on internal structures like the cervix and other abdominal organs. The cervix, a sensitive part of the reproductive system, can react to direct impact or stretching, leading to pain that radiates to the lower abdomen. Positions allowing deeper penetration may increase this pressure-induced discomfort. Vigorous sexual activity can also temporarily strain abdominal muscles, contributing to soreness.

Medical Conditions That Can Cause Pain

When stomach pain during sexual activity persists or is severe, it may indicate an underlying medical condition requiring professional evaluation. Several gynecological conditions are known to cause such discomfort. Endometriosis involves the growth of tissue similar to the uterine lining outside the uterus, often on organs like the ovaries, fallopian tubes, or bowel. During sex, especially with deep penetration, these misplaced tissues can be stretched or stimulated, leading to significant deep pelvic pain.

Pelvic Inflammatory Disease (PID), an infection of the female reproductive organs, can also cause pain during intercourse. This infection, often a complication of sexually transmitted infections (STIs), causes inflammation and scarring in the uterus, fallopian tubes, or ovaries. The inflamed tissues become sensitive, and sexual movements can aggravate them, resulting in lower abdominal pain. Ovarian cysts, fluid-filled sacs on the ovaries, can cause acute or chronic pain. A cyst might rupture or twist during sexual activity, leading to sudden, sharp abdominal pain.

Uterine fibroids, non-cancerous growths within the uterus, can also contribute to discomfort. Depending on their size and location, fibroids can cause pressure or pain, particularly if they are near the cervix or if sexual activity puts direct pressure on them. Inflammation of the cervix, known as cervicitis, can also lead to pain during intercourse. The cervix becomes tender and easily irritated, often due to infections, including STIs, or other irritants.

Beyond gynecological issues, various gastrointestinal conditions can influence abdominal pain during sex. Irritable Bowel Syndrome (IBS), a common disorder affecting the large intestine, can cause symptoms like cramping, abdominal pain, bloating, and gas. Sexual activity, particularly positions that compress the abdomen, can sometimes exacerbate these existing digestive sensitivities, triggering an IBS flare-up. Chronic constipation or other digestive irregularities can similarly lead to discomfort that intensifies during physical exertion or pressure.

Urinary tract conditions, such as Urinary Tract Infections (UTIs), can also present with abdominal pain during or after sex. A UTI causes inflammation in the urinary tract, including the bladder and urethra, making the entire pelvic region tender. The pressure and movement associated with sexual activity can irritate an already inflamed bladder, leading to lower abdominal pain or discomfort, often accompanied by a burning sensation during urination.

Adhesions, which are bands of scar tissue that form between organs, often as a result of previous surgeries or infections, can restrict organ movement. If these adhesions are in the pelvic or abdominal area, sexual activity can stretch or pull on them, causing pain. Certain sexually transmitted infections (STIs) can also cause inflammation in the pelvic region, leading to persistent discomfort or pain during intercourse.

When to Seek Medical Advice

While some causes of stomach pain during sex are temporary, it is important to know when to seek medical advice. Consult a healthcare provider if the pain is severe, persistent, or progressively worsening, as these indicate an underlying issue. Any pain accompanied by other concerning symptoms warrants immediate attention.

Accompanying symptoms include:
Fever
Unusual vaginal discharge
Abnormal bleeding outside of menstruation
Nausea or vomiting
Pain during urination

Such symptom combinations could suggest an infection or a more serious medical condition. If the pain significantly interferes with your daily life, impacts your sexual activity, or is a new and sudden onset symptom, discuss it with a doctor.

Healthcare professionals can conduct a thorough examination, order diagnostic tests, and provide an accurate diagnosis. Openly communicating your symptoms and concerns with a doctor ensures you receive personalized advice and the best possible care.
