STD symptoms: Common STDs and their symptoms
STD symptoms: Common STDs and their symptoms
If you have sex, you may also have an STD, along with subtle or noticeable STD symptoms. Straight or gay, married or single, you're vulnerable to STDs and STD symptoms, whether you engage in oral, anal or vaginal sex.
Although condoms are highly effective for reducing transmission of STDs, no method is foolproof. This is particularly true with certain STDs, such as genital warts and genital herpes.
STD symptoms aren't always obvious. If you think you're experiencing STD symptoms, see a doctor. Some STD symptoms can be treated easily and eliminated, but others require more involved and long-term treatment.
Either way, it's essential to be evaluated, and — if diagnosed with an STD — get treated. It's also essential to inform any partners so that they can be evaluated and treated. If untreated, STDs can increase your risk of acquiring another STD such as HIV. This happens because an STD can stimulate an immune response in the genital area or cause sores, either of which might make HIV transmission more likely. Some untreated STDs can also lead to infertility.
STDs often asymptomatic
You could have an STD and be asymptomatic — without any signs or symptoms. In fact, this happens with a lot of STDs. Even though you have no symptoms, you're still at risk of passing the infection along to your sex partners. That's why it's important to visit your doctor on a regular basis for STD screening, so you can identify a potential infection and get treated for it before passing it along to someone else.
Chlamydia is a bacterial infection of your genital tract. Chlamydia may be difficult for you to detect because early-stage infections often cause few or no signs and symptoms. When they do occur, they usually start one to three weeks after you've been exposed to chlamydia. Even when signs and symptoms do occur, they're often mild and passing, making them easy to overlook.
Signs and symptoms may include:
Gonorrhea is a bacterial infection of your genital tract. The first gonorrhea symptoms generally appear within two to 10 days after exposure. However, some people may be infected for months before signs or symptoms occur. Signs and symptoms of gonorrhea may include:
Trichomoniasis is a common sexually transmitted disease caused by a microscopic, one-celled parasite called Trichomonas vaginalis. This organism spreads during sexual intercourse with someone who already has the infection. The organism usually infects the urinary tract in men, but often causes no symptoms in men. Trichomoniasis typically infects the vagina in women and may cause these signs and symptoms:
HIV is an infection with the human immunodeficiency virus. HIV interferes with your body's ability to effectively fight off viruses, bacteria and fungi that cause disease, and it can lead to AIDS, a chronic, life-threatening disease.
When first infected with HIV, you may have no symptoms at all. Some people develop a flu-like illness, usually two to six weeks after being infected. Early HIV signs and symptoms may include:
These early signs and symptoms usually disappear within a week to a month and are often mistaken for those of another viral infection. During this period, you are very infectious. More persistent or severe symptoms of HIV infection may not appear for 10 years or more after the initial infection.
As the virus continues to multiply and destroy immune cells, you may develop mild infections or chronic signs and symptoms such as:
Signs and symptoms of later stage HIV infection include:
Genital herpes symptoms
Genital herpes is highly contagious and caused by a type of the herpes simplex virus (HSV). HSV enters your body through small breaks in your skin or mucous membranes. Most people with HSV never know they have it, because they have no signs or symptoms. The signs and symptoms of HSV can be so mild they go unnoticed. When signs and symptoms are noticeable, the first episode is generally the worst. Some people never experience a second episode. Other people, however, can experience episodes over a period of decades.
When present, genital herpes signs and symptoms may include:
The initial symptom of genital herpes usually is pain or itching, beginning within a few weeks after exposure to an infected sexual partner. After several days, small, red bumps may appear. They then rupture, becoming ulcers that ooze or bleed. Eventually, scabs form and the ulcers heal.
In women, sores can erupt in the vaginal area, external genitals, buttocks, anus or cervix. In men, sores can appear on the penis, scrotum, buttocks, anus or thighs, or inside the urethra, the tube from the bladder through the penis.
While you have ulcers, it may be painful to urinate. You may also experience pain and tenderness in your genital area until the infection clears. During an initial episode, you may have flu-like signs and symptoms, such as headache, muscle aches and fever, as well as swollen lymph nodes in your groin.
In some cases, the infection can be active and contagious even when sores aren't present.
Genital warts (HPV infection) symptoms
Genital warts, caused by the human papillomavirus (HPV), are one of the most common types of STDs. The signs and symptoms of genital warts include:
Often, however, genital warts cause no symptoms. Genital warts may be as small as 1 millimeter in diameter or may multiply into large clusters.
In women, genital warts can grow on the vulva, the walls of the vagina, the area between the external genitals and the anus, and the cervix. In men, they may occur on the tip or shaft of the penis, the scrotum, or the anus. Genital warts can also develop in the mouth or throat of a person who has had oral sex with an infected person.
Hepatitis A, hepatitis B and hepatitis C are all contagious viral infections that affect your liver. Hepatitis B and C are the most serious of the three, but each can cause your liver to become inflamed.
Some people never develop signs or symptoms. But for those who do, signs and symptoms may occur after several weeks and may include:
Syphilis is a bacterial infection. The disease affects your genitals, skin and mucous membranes, but it may also involve many other parts of your body, including your brain and your heart.
The signs and symptoms of syphilis may occur in four stages — primary, secondary, latent and tertiary.
Signs and symptoms of primary syphilis typically disappear without treatment, but the underlying disease remains and may reappear in the second (secondary) or third (tertiary) stage.
These signs and symptoms may disappear within a few weeks or repeatedly come and go for as long as a year.
Some of the signs and symptoms of tertiary syphilis include:
If you suspect you have an STD, see your doctor
If you suspect you have these or other STDs or that you may have been exposed to one, see your doctor for STD testing. Timely diagnosis and treatment are important to avoid or delay more severe, potentially life-threatening health problems and to avoid infecting others.
