HIV living with treatment in teenagers

Overview

HIV (human immunodeficiency virus) is a virus that attacks the body's immune system, making it harder to fight infections. With modern treatment, teenagers with HIV can live long, healthy lives. Treatment lowers the amount of virus in the blood to very low levels, which keeps the immune system strong and stops the virus from being passed to others.

HIV is not common among teenagers in the UK overall, but it does affect some young people, especially those born to mothers with HIV or those who acquire it through risky behaviours.

Teenagers with HIV may be born with the virus (perinatal transmission) or acquire it later through unprotected sex, sharing needles, or other blood contact. It affects all genders, ethnicities, and backgrounds.

Symptoms

Common symptoms

• Many teenagers with HIV have no symptoms, especially if treatment is working well.
• Some may feel tired, have swollen lymph nodes (glands), or get infections more often.
• Weight loss, night sweats, and fever can occur if the virus is not controlled.

Symptoms in children

• Children with HIV may have slow growth, delayed puberty, or frequent infections like ear infections or pneumonia.

Symptoms in older adults

• This section is for teenagers, so not applicable. However, untreated HIV in older adults can lead to more severe infections and cancers.

Causes

Main causes

• HIV is caused by the human immunodeficiency virus, which attacks CD4 cells (a type of white blood cell).
• It is spread through body fluids like blood, semen, vaginal fluids, and breast milk.
• Teenagers can get HIV from their mother during pregnancy, birth, or breastfeeding, or through unprotected sex or sharing needles.

Risk factors

• Born to a mother with HIV who did not receive treatment during pregnancy
• Having unprotected sex (without condoms) with someone who has HIV and is not on effective treatment
• Sharing needles, syringes, or other injecting equipment
• Having a sexual partner who is at high risk for HIV

When to see a doctor

See a doctor urgently if:

• If you have symptoms of a serious infection (high fever, trouble breathing, severe pain)
• If you have suicidal thoughts or feel very depressed
• If you miss several doses of your HIV medicine and are worried about it

Book a routine appointment if:

• Every 3-6 months for blood tests to check HIV viral load and CD4 count
• If you start a new relationship and want to talk about prevention (PrEP) or safer sex
• If you experience side effects from your HIV medicine

Diagnosis

HIV is diagnosed with a blood test that looks for antibodies to the virus or the virus itself. In teenagers, testing is offered confidentially. A positive result is always confirmed with a second test.

Tests that may be done

• HIV antibody/antigen test (4th generation test) – detects virus and antibodies
• Viral load test – measures amount of virus in blood
• CD4 count – measures immune system strength

What to expect at your appointment

If you are diagnosed with HIV, you will be referred to a specialist clinic. The doctor will talk with you about starting treatment, explain what to expect, and help you plan how to take your medication every day. You will have regular check-ups and support from a team including nurses, pharmacists, and counsellors.

Treatment

HIV treatment is called antiretroviral therapy (ART). It usually involves taking a combination of at least three medications every day. ART does not cure HIV, but it reduces the virus to undetectable levels, protects your immune system, and prevents transmission to others. It is important to take every dose on time.

Self-care at home

• Take your HIV medication exactly as prescribed, every day, at the same time.
• Use a pillbox or phone alarm to help remember doses.
• Stay in regular contact with your clinic team.
• Practice safer sex (use condoms) to protect yourself and your partner from other infections.
• Consider talking to a counsellor or peer support group – you are not alone.

Medical treatments

Treatment involves daily oral medications (tablets or capsules) that are prescribed by a specialist doctor. The specific combination is chosen based on your needs, other health conditions, and potential side effects. Some teenagers may be able to use long-acting injectable treatments given every month or two, but this depends on individual suitability. Always follow your doctor's advice. Do not change or stop treatment without talking to your clinic first.

When is surgery considered?

HIV itself usually does not require surgery. Surgery may be needed for complications of HIV (like removing a tumour) or for unrelated conditions. If you need surgery, tell the surgical team about your HIV so they can adjust your care safely.

Living with this condition

Living with HIV as a teenager means taking daily medication, attending clinic appointments, and looking after your overall health. With treatment, you can go to school, play sports, hang out with friends, and plan for the future. You do not need to tell everyone about your HIV – only who you feel safe telling.

Lifestyle tips

• Get enough sleep (8-10 hours per night) to help your immune system.
• Avoid alcohol and recreational drugs, as they can interfere with HIV medicine.
• Stay active – exercise helps your mood and immune health.
• Manage stress through hobbies, talking to friends, or mindfulness.

Diet and exercise

Eat a balanced diet with plenty of fruits, vegetables, whole grains, and lean proteins. There is no special HIV diet, but a healthy diet helps your body fight infections. Regular exercise like walking, cycling, or swimming is encouraged. Talk to your doctor before starting any intense workout plan.

Mental health and emotional wellbeing

Being a teenager with HIV can bring up feelings of fear, sadness, or shame. It is normal to feel anxious about telling others or about your health. Depression and anxiety are common in teens with chronic illnesses. If you feel overwhelmed, hopeless, or have thoughts of hurting yourself, tell a trusted adult or call a crisis helpline immediately. You are not alone – support is available.

Prevention

HIV transmission can be prevented. If you have HIV and are on effective treatment with an undetectable viral load, you cannot pass the virus to others. Using condoms every time you have sex and not sharing needles also prevent transmission. If you do not have HIV, PrEP (pre-exposure prophylaxis) is a daily pill that can prevent infection – ask your doctor or clinic.

Vaccines

There is no vaccine for HIV, but teenagers with HIV should get all routine vaccines (like HPV, hepatitis B, and flu) as recommended by their doctor.

Screening programmes

Any teenager who has had unprotected sex or shared needles should get tested for HIV. Testing is confidential and often free at sexual health clinics. If you are pregnant and have HIV, treatment can prevent passing the virus to your baby.

Complications

If left untreated

• Weakened immune system (low CD4 count) leading to serious infections (like pneumonia, tuberculosis)
• Increased risk of certain cancers (like lymphoma or cervical cancer)
• Weight loss, chronic diarrhoea, and fatigue (wasting syndrome)
• Brain and nerve problems (dementia, memory loss) – rare in teens but possible
• Passing HIV to others if viral load is high

Long-term outlook

With modern treatment, the outlook for teenagers with HIV is excellent. If you take your medication every day and attend clinic regularly, you can expect to live a long, healthy life – just like anyone else your age. You can have relationships, children, and a career. HIV is a manageable condition, not a death sentence. Many teenagers with HIV go to university and achieve their dreams.
