A stroke is a life-threatening medical emergency that occurs when there is an issue with blood flow to the brain. This can be due to a blocked blood vessel or bleeding in the brain. While strokes are typically associated with old age, they can happen to anyone at any time. So, can a stroke be caused by an STD?
What You'll Learn
Can STDs cause blood clots?
Sexually transmitted diseases (STDs) are communicable infections that are passed from person to person during sex through vaginal intercourse, anal sex, oral sex, or skin-to-skin contact. STDs are caused by bacteria, viruses, or parasites, and can lead to various symptoms, including abnormal vaginal discharge, pain during urination, and bleeding between periods.
While STDs themselves do not directly cause blood clots, they can increase the risk of blood clots forming in the body, which can subsequently lead to more severe health complications. For example, untreated STDs such as chlamydia and gonorrhoea can lead to pelvic inflammatory disease (PID), an infection of the reproductive organs. PID can cause abdominal pain, fever, painful intercourse, irregular menstrual cycles, and abnormal vaginal discharge. If left untreated, PID can also lead to infertility.
In addition, STDs can also increase the risk of atherosclerosis, a disease characterised by plaque buildup in the inner walls of arteries. This plaque buildup can lead to the narrowing of arteries, reducing blood flow to vital organs, including the brain. This condition is known as ischemic stroke, which accounts for about 80% of all strokes. Ischemic strokes occur when blood flow to the brain is blocked, typically by a piece of plaque or a blood clot.
Furthermore, STDs can also contribute to chronic inflammation, which has been linked to ischemic stroke. Research indicates that inflammation can damage blood vessels and promote atherosclerosis. Additionally, ischemic stroke can further lead to inflammation, causing more damage to brain cells.
While STDs themselves might not directly cause blood clots, they can increase the risk of blood clot formation by causing infections and promoting chronic inflammation. These blood clots can then lead to ischemic strokes, which are a life-threatening condition requiring immediate medical attention. Therefore, it is essential to seek testing and treatment for STDs to prevent potential complications and maintain overall health.

Can STDs cause brain aneurysms?
A stroke occurs when there is an issue with blood flow to the brain, such as blocked blood vessels or bleeding in the brain. The most common type of stroke is an ischemic stroke, which is caused by a blockage in the brain, usually due to a blood clot. The other type is a hemorrhagic stroke, which is caused by sudden bleeding in the brain.
A brain aneurysm is a bulge in a weak area of a blood vessel in or around the brain. It can cause symptoms if it puts pressure on nearby nerves or brain tissue. If the aneurysm ruptures, it can lead to bleeding in the brain, which is life-threatening and requires emergency medical treatment.
While STDs can increase the risk of stroke by causing inflammation and damage to blood vessels, there is no direct link between STDs and brain aneurysms. Brain aneurysms are typically caused by high blood pressure, substance use (especially cocaine), and excessive alcohol consumption. However, STDs can indirectly increase the risk of a brain aneurysm rupturing by causing inflammation and damage to blood vessels, which can lead to a hemorrhagic stroke.
In summary, while STDs themselves do not cause brain aneurysms, they can contribute to the conditions that increase the risk of aneurysm rupture and subsequent stroke.

Can STDs cause high blood pressure?
Sexually transmitted diseases (STDs) are often associated with immediate health consequences, such as painful symptoms and the risk of long-term complications like infertility. However, recent studies have found a link between certain STDs and high blood pressure. Chlamydia and gonorrhea, for instance, can cause inflammation in the body, which can lead to an increase in blood pressure. People with these STDs are up to three times more likely to develop high blood pressure than those without.
High blood pressure is a significant risk factor for cardiovascular disease (CVD), which is the number one cause of death in the United States and worldwide. Hypertension, along with tobacco use, obesity, and other lifestyle behaviours, contributes to this. Additionally, high blood pressure is a leading cause of strokes.
Therefore, it is crucial to get tested for STDs and high blood pressure to maintain overall health and well-being. Untreated STDs can lead to severe complications, and high blood pressure increases the risk of heart disease, stroke, and other health issues. Addressing multiple risk behaviours, including moderate alcohol consumption and weight control, is essential for improving blood pressure among individuals at risk for HIV/STIs.

Can STDs cause inflammation?
Sexually transmitted infections (STIs) are highly contagious and can be caused by various bacteria, viruses, or parasites that infect the body. STIs can cause inflammation, which is a strong predictor of HIV acquisition risk.
STIs can cause inflammation in the genital tract, perturbing the normal function of the mucosal barrier against HIV. The mucosal barrier is the first line of defence against invading microorganisms such as HIV. STIs can also cause inflammation in the genital tract, leading to pathology throughout the genital tract, including pelvic inflammatory disease, ectopic pregnancy, and infertility.
The types of mucosal responses to STIs vary and can be asymptomatic or result in the formation of discharge, ulcers, and/or warts. While the aim of this response is to clear the invading microbes, these responses are often evaded or cause pathology that impairs barrier integrity, increasing HIV access to target cells in the sub-mucosa.
STIs can also induce inflammation through interactions with the epithelial barrier and immune cells at the site of infection. There are several molecular pathways involved in the inflammatory response to a diverse range of STIs, which likely function to cause pathology by weakening the mucosal barrier.
STIs can also use immune evasion strategies to dampen the immune response and enhance their persistence. For example, in C. trachomatis infection, neutrophils are among the first immune cells to be recruited to the site of infection. However, the pathogen employs a strategy of delayed apoptosis to reduce the neutrophil sensitivity towards apoptosis stimuli, contributing to pathogen persistence.
In summary, STIs can cause inflammation, which can have serious health consequences, including an increased risk of HIV acquisition.

Can STDs cause atherosclerosis?
Atherosclerosis is a chronic inflammatory disease that involves the development of abnormalities called lesions in the walls of arteries. It is characterised by a gradual buildup of plaque—a sticky substance made of fat, cholesterol, calcium, and other substances—in the walls of arteries, causing them to harden and narrow. This buildup restricts blood flow to organs and tissues, increasing the risk of blood clots, heart attacks, and strokes.
While the exact cause of atherosclerosis is unknown, several risk factors have been identified, including abnormal cholesterol levels, elevated levels of inflammatory biomarkers, high blood pressure, diabetes, smoking, obesity, genetic factors, family history, lifestyle habits, and an unhealthy diet.
Sex, age, and race also play a role in the development of atherosclerosis and the likelihood of experiencing a stroke. Men are more likely to experience a stroke at younger ages, while women tend to have a higher lifetime risk due to their longer life expectancy. The risk of stroke also varies across racial and ethnic groups, with a higher prevalence among Black, Alaska Native, American Indian, and Hispanic adults compared to white adults in the United States.
While there is no direct link between STDs and atherosclerosis, certain STDs can increase the risk of atherosclerosis by impacting the aforementioned risk factors. For example, some STDs can cause inflammation, elevated cholesterol levels, or damage to blood vessels, all of which are risk factors for atherosclerosis.
Additionally, people living with STDs may be more likely to engage in unhealthy lifestyle habits, such as smoking, excessive alcohol consumption, or illegal drug use, which are also risk factors for atherosclerosis. Furthermore, the stress and anxiety associated with living with an STD can further increase the risk of atherosclerosis and stroke.
Therefore, while STDs may not directly cause atherosclerosis, they can indirectly contribute to its development and increase the likelihood of experiencing a stroke by exacerbating existing risk factors.
