Lean Fatty Liver: Why Slim People Get It and What Helps

By -

Lean fatty liver surprises many people. You are not overweight, you may even be told you look thin, and yet an ultrasound report mentions a fatty liver. This is common in India and the rest of South Asia, and it has a clear explanation. This guide covers why it happens, how it is checked, and the practical steps that help when the scale does not seem to be the problem. Quick answer: Lean fatty liver means fat has built up in the liver in someone with a normal body mass index. In South Asians it is often driven by fat stored around the waist and inside the abdomen, insulin resistance, and a diet heavy in refined carbohydrates and sugar. It is assessed the same way as other fatty liver, and a modest weight loss of around 3 to 5%, better food quality and regular exercise usually help. Key takeaways ✅ A normal BMI does not rule out fatty liver, especially in South Asians. ✅ Waist size often tells more than weight. ✅ The liver scarring check (FIB-4, then a stiffness scan if n...

HIV and AIDS: Symptoms, Tests, Treatment and Prevention

By -
✓ Medically reviewed by Dr. Ram Kumar, MBBS, MD

HIV (human immunodeficiency virus) attacks the immune system's CD4 cells. Without treatment it slowly weakens the body's defences until serious infections and cancers develop, the stage called AIDS. Today HIV is a manageable long-term condition: with daily treatment, people with HIV can live a normal lifespan, and once the virus is fully suppressed they do not pass it on through sex. In India, testing and treatment are free through the National AIDS Control Programme.

Quick answer: HIV often causes no symptoms for years, so the only way to know is a blood test. Some people get a flu-like illness 2 to 4 weeks after infection. Modern tests detect most infections within about 6 weeks, and a repeat test at 3 months confirms a negative result. HIV is prevented by condoms, never sharing needles, testing in pregnancy, and emergency medicine (PEP) started within 72 hours of an exposure. Treatment (ART) is free and lifelong in India.

Key takeaways

  • ✅ Get tested if you have ever had unprotected sex, shared needles or had an STI.
  • ✅ Free, confidential testing is available at Integrated Counselling and Testing Centres (ICTCs).
  • ✅ Undetectable = Untransmittable: suppressed HIV is not passed on through sex.
  • ✅ National AIDS helpline: 1097 (toll-free).

How HIV spreads, and how it does not

HIV can spread through HIV does not spread through
Unprotected vaginal or anal sexHugging, shaking hands or kissing
Sharing needles or syringesSharing food, plates, toilets or swimming pools
From mother to baby during pregnancy, birth or breastfeedingMosquito or insect bites
Unscreened blood transfusion (very rare now)Coughing, sneezing or saliva

Symptoms of HIV

HIV moves through stages, and symptoms are similar in men and women.

1. Early (acute) HIV, 2 to 4 weeks after infection: many people have a short flu-like illness, while others have none.

  • Fever, sore throat and tiredness
  • Swollen glands in the neck, armpits or groin
  • A red, non-itchy rash
  • Muscle and joint aches, headache
  • Mouth ulcers, diarrhoea

2. Chronic (silent) stage: the virus keeps multiplying and damaging the immune system, often for years with few or no symptoms. The person can still pass on HIV during this stage.

3. Advanced HIV and AIDS: when CD4 cells fall below 200 per cubic millimetre, or certain infections appear, it is called AIDS. Signs include:

  • Weight loss and long-lasting fever or night sweats
  • Diarrhoea lasting more than a month
  • Oral thrush (white patches in the mouth), recurrent shingles or skin infections
  • Tuberculosis, pneumonia and other opportunistic infections

In women, recurrent vaginal yeast infections and pelvic infections can be a clue. None of these symptoms prove HIV; a test is the only way to know.

Tests for HIV

Test What it detects When it turns positive
Antigen/antibody test (4th generation ELISA or CLIA)HIV p24 antigen and antibodiesUsually 2 to 6 weeks after exposure
Rapid antibody testsAntibodies onlyUsually within 3 months; result in 20 minutes
HIV RNA (viral load) or PCRThe virus's genetic materialAbout 10 days to 4 weeks; used for early diagnosis, babies born to mothers with HIV, and monitoring treatment
CD4 countStrength of the immune systemUsed after diagnosis, not for diagnosis

In India, a positive screening test is always confirmed using a set of three different tests before a diagnosis is given. The window period is the time between infection and a positive test: if you test soon after a risk, a negative result should be repeated at 3 months. Testing is voluntary and confidential, and your results cannot be shared without your consent under the HIV and AIDS (Prevention and Control) Act, 2017.

Treatment: antiretroviral therapy (ART)

India follows a "treat all" policy: everyone diagnosed with HIV is offered ART straight away, regardless of CD4 count, free of charge at ART centres. Most adults start a once-daily tablet combination containing dolutegravir. Treatment is lifelong and works best when doses are not missed.

  • Viral load is checked regularly. The goal is an undetectable level, usually reached within about six months.
  • People with an undetectable viral load do not transmit HIV sexually (U=U).
  • Pregnant women with HIV who take ART, together with preventive medicine for the baby, reduce the chance of passing HIV to the baby to very low levels.
  • TB screening and preventive TB treatment are part of routine HIV care, because TB is the leading cause of illness in people with HIV.

How to prevent HIV

  • Use condoms correctly every time
  • Never share needles, syringes or razors; insist on sterile equipment for injections, tattoos and piercings
  • Get tested with your partner, and treat other STIs promptly
  • Test in every pregnancy, which is routine in India
  • PEP (post-exposure prophylaxis): if you think you have been exposed, for example after unprotected sex, sexual assault or a needle-stick injury, go to a hospital or ART centre immediately. PEP must start within 72 hours, ideally within a few hours, and is taken for 28 days.
  • PrEP (pre-exposure prophylaxis): daily medicine for people at ongoing high risk, available through some clinics and programmes. Ask a doctor whether it suits you.

Frequently asked questions

Is there a cure for HIV?

Not yet. ART controls the virus so well that most people on treatment live long, healthy lives, but it must be taken every day.

How soon after exposure can I test?

A 4th-generation test can pick up most infections by about 6 weeks. Retest at 3 months to be certain. If the exposure was in the last 72 hours, seek PEP first.

Can a mother with HIV have a healthy baby?

Yes. With ART during pregnancy and breastfeeding and preventive medicine for the baby, the vast majority of babies are born free of HIV.

What is the difference between HIV and AIDS?

HIV is the virus. AIDS is the advanced stage of untreated HIV infection. With early treatment, most people with HIV never develop AIDS.

CBC Blood Test: WBC Count, Platelet Count, Normal Ranges and What Results Mean

By -
A complete blood count (CBC) is the most commonly ordered blood test. From one small tube of blood it measures the three types of blood cells: red blood cells that carry oxygen, white blood cells (leucocytes) that fight infection, and platelets that help blood clot. This guide explains what each part of the report means, normal ranges, and common reasons for high or low counts, along with the related bleeding time test. Quick answer: In adults, a normal white blood cell count is roughly 4,000 to 11,000 cells per microlitre, platelets 150,000 to 450,000 per microlitre, and hemoglobin about 13 to 17 g/dL in men and 12 to 15 g/dL in women. A high WBC count usually points to infection or inflammation; a low one can follow viral infections, some medicines or bone marrow problems. Low platelets are common in dengue and some other infections. No fasting is needed for a CBC. Key takeaways ✅ Results slightly outside the range are common and often not significant; patterns matter mo...

Malaria: Symptoms, Blood Tests and Treatment in India

By -
Malaria is a fever caused by Plasmodium parasites that spread through the bite of an infected female Anopheles mosquito. It is fully curable when it is confirmed early with a blood test and treated with the right medicines, but it can turn serious within a day or two, especially in children and pregnant women. This guide explains the symptoms, which tests confirm it, how it is treated in India, and when a fever needs urgent care. Quick answer: Any fever in or after a stay in a malaria area should be tested the same day with a rapid diagnostic test (RDT) or a blood smear under the microscope. Symptoms usually start 7 to 30 days after the bite and include fever with chills, sweating, headache and body ache. Treatment depends on the species: P. vivax needs a medicine to clear the blood plus a 14-day course to prevent relapse, and P. falciparum needs an artemisinin-based combination. Confusion, fits, breathlessness, dark urine or repeated vomiting mean hospital care now. Key tak...
