What is an STI?

Sexually transmitted diseases (STDs), also referred to as sexually transmitted infections (STDs) or venereal diseases (VD), are infections that are spread by sexual activity - typically vaginal, anal and oral sex. Frequently, STIs initially are symptomless, which is why it is important to get screened regularly.

  • urinating
  • Bleeding between periods or Heavy menstrual bleeding
  • Swollen and painful testicles
  • Anal itching
  • Painful bowel movements

How you can prevent STD infection

The only way to ensure that you never catch an STI or an STD is to have no sexual contact. Given that for most, this is not a very practical option, there are ways to minimise your risk of contracting a sexual disease:

  • When you meet a new partner, discuss your sexual history openly before engaging in sexual activity.
  • Have regular STI and STD tests, especially if you have changed sexual partners or have multiple sexual partners. You should ask any new sexual partner to undergo screening as well.
  • Use protection with a condom during vaginal, oral or anal sex.
  • You could consider being vaccinated against Hepatitis B and HPV.
  • If you think you are at higher risk of contracting HIV, you could consider taking the medication PrEP.

Can an STD be detected from a blood test?

Most STDs can be tested through a simple blood test and urine sample. At private GUM clinic in London, experienced doctors can check for the following STDs:

  • Chlamydia
  • Gonorrhoea
  • Mycoplasma Genitalium
  • Syphilis
  • Herpes
  • HIV
  • Hepatitis

In some cases, blood tests aren’t as accurate as other forms of testing. It may also take a month or longer after being exposed to certain STIs for blood tests to be reliable. For example, if HIV is contracted, it can take up to 28 days to a few months for tests to detect the infection.

What is the best way to protect against STIs?

The best way to protect against contracting or transmitting an STI is to use protection every time you have sex. Remember that having an STI once does not grant immunity; you can contract the same infection again. While no one wants to believe they have an STI, seeking treatment from a reputable STD testing clinic early provides the best chance of a swift recovery. Practicing safe sex remains the most effective way to prevent contracting an STI.
