What Can Happen If an STI Is Left Untreated?
Sexually transmitted infections (STIs) are common, and some can cause little or no noticeable symptoms. This means it is possible to have an infection without knowing it.
While many STIs can be treated effectively, leaving certain infections untreated can sometimes lead to health complications. This is why testing, diagnosis and appropriate treatment are important parts of looking after your sexual health.
Pelvic Inflammatory Disease
Some untreated STIs, including chlamydia and gonorrhoea, can spread to the upper reproductive organs and cause pelvic inflammatory disease (PID).
PID can cause symptoms such as pelvic or lower abdominal pain, pain during sex, unusual bleeding or vaginal discharge. In some cases, PID can cause longer-term complications if it is not treated.
Fertility Problems
Untreated infections such as chlamydia and gonorrhoea can sometimes cause damage to the reproductive system.
This can increase the risk of fertility problems in the future. Early diagnosis and treatment can help reduce the risk of complications.
Ongoing Symptoms and Discomfort
An untreated STI may cause symptoms that continue or become more noticeable over time.
Depending on the infection, these can include pain, discomfort, unusual discharge, sores, irritation or other changes.
If you notice anything unusual, seeking professional advice and getting tested can help you find out what is causing the symptoms.
Passing an STI to a Partner
You can have an STI without experiencing any symptoms and still pass the infection to a sexual partner.
Getting tested can help you understand your sexual health status and take appropriate steps to protect yourself and your partners.
The Good News: Treatment Is Available
If you are worried that you may have an STI, try not to panic.
Many STIs can be treated effectively, and getting tested means you can receive the appropriate advice, treatment and support if you need it.
There is no reason to feel embarrassed about seeking help. Sexual health is part of your overall health, and getting tested is a positive step towards looking after yourself.
