What Does Hiv Aids Do To Your Body

How To Avoid Getting Hiv

Gilead HIV: What HIV Does Inside the Body

Abstinence, or not having sex, is the only type of protection that works every time. But if you are having sex, you can lower your risk if you:

  • Use a condom every time you have sex
  • Get tested for HIV and STDs
  • Limit the number of people you have sex with
  • Donât inject yourself with drugs

Talk to your doctor right away if you think youâve been exposed to the virus. They can help you figure out next steps.

Does Hiv Viral Load Affect Getting Or Transmitting Hiv

Yes. Viral load is the amount of HIV in the blood of someone who has HIV. Taking HIV medicine daily as prescribed can make the viral load very lowso low that a test cant detect it .

People with HIV who take HIV medicine daily as prescribed and get and keep an undetectable viral load have effectively no risk of transmitting HIV to an HIV-negative partner through sex.

HIV medicine is a powerful tool for preventing sexual transmission of HIV. But it works only as long as the HIV-positive partner gets and keeps an undetectable viral load. Not everyone taking HIV medicine has an undetectable viral load. To stay undetectable, people with HIV must take HIV medicine every day as prescribed and visit their healthcare provider regularly to get a viral load test. Learn more.

What Are The Factors That Affect Disease Progression

The most important factor affecting HIV progression is the ability to achieve viral suppression. Taking antiretroviral therapy regularly helps many people slow the progression of HIV and reach viral suppression.

However, a variety of factors affect HIV progression, and some people progress through the phases of HIV more quickly than others.

Factors that affect HIV progression can include:

  • Ability to achieve viral suppression. Whether someone can take their antiretroviral medications and achieve viral suppression is the most important factor by far.
  • Age when symptoms start. Being older can result in faster progression of HIV.
  • Health before treatment. If a person had other diseases, such as tuberculosis, hepatitis C, or other sexually transmitted diseases , it can affect their overall health.
  • Timing of diagnosis. Another important factor is how soon a person was diagnosed after they contracted HIV. The longer between their diagnosis and treatment, the more time the disease has to progress unchecked.
  • Lifestyle. Practicing an unhealthy lifestyle, such as having a poor diet and experiencing severe stress, can cause HIV to progress more quickly.
  • Genetic history. Some people seem to progress more quickly through their disease given their genetic makeup.

Some factors can delay or slow the progression of HIV. These include:

Living a healthy lifestyle and seeing a healthcare provider regularly can make a big difference in a persons overall health.

Hiv Effects On The Kidneys

High blood pressure and diabetes are both related to HIV, and both are major causes of kidney disease. The healthy diet and exercise habits that are good for your heart will help keep your blood pressure and blood sugar under control. That helps protect your kidneys, too.

Some HIV medications can damage your kidneys. If you already have kidney problems, your doctor may want to avoid those drugs or keep a close eye on their effects.

Your doctor will need to check your kidneys regularly because you might not notice the signs of kidney disease.

What Is The Outlook For Someone With Hiv/aids

How to get tested for HIV

If you are diagnosed with HIV and you start ART soon after, your immune system will not be as compromised. If you continue to take your medicines every day, your outlook is very good.

ART can keep blood levels undetectable but cannot entirely rid the body of the virus . If you do not keep up on your medication, the virus goes back into the blood.

If you have HIV and dont treat it, it can take about 10 years to lead to AIDS. If you have AIDS and dont treat it, the survival rate is about three years.

It is so important to know that people who have HIV and who follow treatment guidelines are able to live full lives for nearly as long as HIV-negative people.

HIV spreads when infected blood or body fluids enter the body. This can happen:

HIV also can pass from mother to child during pregnancy, childbirth, or breastfeeding.

HIV is NOT spread through:

  • pee, poop, spit, throw-up, or sweat
  • coughing or sneezing
  • sharing eating utensils or drinking glasses

Symptoms Of Hiv/aids And Stages

Many people donât have symptoms at first, and sometimes even for years or decades. But there are signs that can happen, such as flu-like symptoms soon after you become infected with HIV. Even if you donât feel sick, HIV damages the immune system. It hijacks infection-fighting white blood cells called CD4 cells and uses them to churn out thousands of copies of itself. Without treatment, HIV destroys so many of these cells that your body canât protect you from life-threatening infections. If your CD4 count drops below 200, you have AIDS.

There are three stages of HIV infection:

Stage 1: This the earliest stage. You may also hear it called the âacuteâ stage. You might have a fever, rash, fatigue, chills, and other flu-like symptoms. But you might not have any symptoms. If you do, they may start 2-4 weeks after youâre infected. During this time, the virus quickly makes many copies of itself.

Stage 2: During this stage, HIV continues to reproduce, and it slowly damages your immune system over time. You might not feel sick or have symptoms. But HIV isnât gone, and you can still spread it to other people. This stage can last for years or even decades.

Stage 3: This is when you have AIDS. Your immune system has been severely damaged, leaving you vulnerable to other illnesses. With AIDS, many people have symptoms such as chills, fever, sweats, swollen lymph glands, weakness, and weight loss.

How Is Hiv Spread

The spread of HIV from person to person is called HIV transmission. HIV is spread only through certain body fluids from a person who has HIV. These body fluids include:

  • Blood
  • Rectal fluids
  • Breast milk

HIV transmission is only possible through contact with HIV-infected body fluids. In the United States, HIV is spread mainly by:

  • Having anal or vaginal sex with someone who has HIV without using a condom or taking medicines to prevent or treat HIV
  • Sharing injection drug equipment , such as needles or syringes, with someone who has HIV

The spread of HIV from a woman with HIV to her child during pregnancy, childbirth, or breastfeeding is called perinatal transmission of HIV. For more information, read the HIVinfo fact sheet on Preventing Perinatal Transmission of HIV.

You cannot get HIV by shaking hands or hugging a person who has HIV. You also cannot get HIV from contact with objects, such as dishes, toilet seats, or doorknobs, used by a person with HIV. HIV is not spread through the air or water or by mosquitoes, ticks, or other blood-sucking insects. Use the HIVinfo You Can Safely ShareWith Someone With HIV infographic to spread this message.

Is There A Cure For Aids

AIDS, HIV & STDs : How Does AIDS Affect the Body?

There is no cure for AIDS. There are drugs that can slow down the HIV virus, and slow down the damage to your immune system. There is no way to clear the HIV out of your body.

Other drugs can prevent or treat opportunistic infections . In most cases, these drugs work very well. The newer, stronger ARVs have also helped reduce the rates of most OIs. A few OIs, however, are still very difficult to treat. See Fact Sheet 500 for more information on opportunistic infections.

Symptoms Of Hiv Infection

Most people experience a short flu-like illness 2 to 6 weeks after HIV infection, which lasts for a week or 2.

After these symptoms disappear, HIV may not cause any symptoms for many years, although the virus continues to damage your immune system.

This means many people with HIV do not know they’re infected.

Anyone who thinks they could have HIV should get tested.

Some people are advised to have regular tests as they’re at particularly high risk.

How Are Hiv And Aids Treated

Medicines can help people with HIV stay healthy. They can also prevent HIV from progressing to AIDS.

Health care providers prescribe a combination of different medicines for people with HIV and AIDS. They must be taken exactly as prescribed or they won’t work. These medicines:

  • help keep the number of CD4 cells high
  • reduce the viral load of HIV

Regular blood tests will check the number of CD4 cells in the body and the viral load.

If an HIV-positive person’s CD4 count gets low, doctors prescribe daily antibiotics. This prevents pneumocystis pneumonia, which happens in people with weakened immune systems.

What Are The Symptoms Of Hiv/aids

The first signs of HIV infection may be flu-like symptoms:

  • Swollen lymph nodes
  • Mouth ulcers

These symptoms may come and go within two to four weeks. This stage is called acute HIV infection.

If the infection is not treated, it becomes chronic HIV infection. Often, there are no symptoms during this stage. If it is not treated, eventually the virus will weaken your body’s immune system. Then the infection will progress to AIDS. This is the late stage of HIV infection. With AIDS, your immune system is badly damaged. You can get more and more severe infections. These are known as opportunistic infections .

Some people may not feel sick during the earlier stages of HIV infection. So the only way to know for sure whether you have HIV is to get tested.

How Is Aids Diagnosed

HIV Counselling

Symptoms such as fever, weakness, and weight loss may be a sign that a persons HIV has advanced to AIDS. However, a diagnosis of AIDS is based on the following criteria:

  • A drop in CD4 count to less than 200 cells/mm3. A CD4 count measures the number of CD4 cells in a sample of blood.OR
  • The presence of certain opportunistic infections.

Although an AIDS diagnosis indicates severe damage to the immune system, HIV medicines can still help people at this stage of HIV infection.

Start Treatment As Soon As Possible After Diagnosis

  • HIV medicine is recommended for all people with HIV, regardless of how long theyve had the virus or how healthy they are.
  • Talk to your health care provider about any medical conditions you may have or any other medicines you are taking.
  • Let your health care provider know if you or your partner is pregnant or thinking about getting pregnant. They will determine the right type of HIV medicine that can help prevent transmitting HIV to your baby.

What if I delay treatment?

  • HIV will continue to harm your immune system.
  • This will put you at higher risk for developing AIDS. Learn more about AIDS and opportunistic infections.
  • This will put you at higher risk for transmitting HIV to your sexual and injection partners.

How Do I Know If I Have Hiv

The only way to know for sure if you have HIV is to get tested. Testing is relatively simple. You can ask your health care provider for an HIV test. Many medical clinics, substance abuse programs, community health centers, and hospitals offer them too. You can also buy a home testing kit at a pharmacy or online.

To find an HIV testing location near you, use the HIV Services Locator.

HIV self-testing is also an option. Self-testing allows people to take an HIV test and find out their result in their own home or other private location. You can buy a self-test kit at a pharmacy or online. Some health departments or community-based organizations also provide self-test kits for free.

Read the U.S. Food and Drug Administrations fact sheet on the OraQuick In-Home HIV Test, the only FDA-approved in-home HIV test.

The coronavirus pandemic has made it more difficult for some people to access traditional places where HIV testing is provided. Self-testing allows people to get tested for HIV while still following stay-at-home orders and social distancing practices. Ask your local health department or HIV service organization if they offer self-testing kits.

What Is Hiv And Aids

HIV stands for human immunodeficiency virus, which is the virus that causes HIV infection. The abbreviation HIV can refer to the virus or to HIV infection.

AIDS stands for acquired immunodeficiency syndrome. AIDS is the most advanced stage of HIV infection.

HIV attacks and destroys the infection-fighting CD4 cells of the immune system. The loss of CD4 cells makes it difficult for the body to fight off infections and certain cancers. Without treatment, HIV can gradually destroy the immune system and HIV infection advances to AIDS.

The Effects Of Hiv On The Body

HIV: What’s Going on Inside Your Body

Most people are likely familiar with HIV, but they may not know how it can affect the body.

HIV destroys CD4 cells , which are critical to the immune system. CD4 cells are responsible for keeping people healthy and protecting them from common diseases and infections.

As HIV gradually weakens the bodys natural defenses, signs and symptoms will occur.

Find out what happens when the virus enters the body and interrupts its systems.

Once HIV enters the body, it launches a direct attack on the immune system.

How quickly the virus progresses will vary by:

  • a persons age
  • how quickly theyre diagnosed

The timing of their treatment can make a huge difference as well.

HIV targets the types of cells that would normally fight off an invader such as HIV. As the virus replicates, it damages or destroys the infected CD4 cell and produces more virus to infect more CD4 cells.

Without treatment, this cycle can continue until the immune system is badly compromised, leaving a person at risk for serious illnesses and infections.

Acquired immunodeficiency syndrome is the final stage of HIV. At this stage, the immune system is severely weakened, and the risk of contracting opportunistic infections is much greater.

However, not everyone with HIV will go on to develop AIDS. The earlier a person receives treatment, the better their outcome will be.

Early on, HIV symptoms may be mild enough to be dismissed.

Hiv Effects On The Skeletal System

People who have the virus tend to lose bone faster than people who donât. Your bones may get brittle and can break more easily. Your hips, especially, may hurt and feel weak.

Things that might cause this include the virus itself, the inflammation it causes, the medicines you take to treat HIV or related illnesses , and an unhealthy lifestyle. It might also be from a vitamin D deficiency, which is common in people who have HIV.

To help keep your bones in good shape:

  • Make sure you get plenty of calcium and vitamin D.
  • Exercise in ways that put weight on your bones, like walking or lifting weights.
  • Don’t smoke, and limit how much alcohol you drink.
  • Ask your doctor to check your vitamin D level.

Talk to your doctor about supplements or other medications to help your bones.

Can Hiv/aids Be Prevented

You can reduce the risk of spreading HIV by

  • Getting tested for HIV
  • Choosing less risky sexual behaviors. This includes limiting the number of sexual partners you have and using latex condoms every time you have sex. If your or your partner is allergic to latex, you can use polyurethane condoms.
  • Getting tested and treated for sexually transmitted diseases
  • Not injecting drugs
  • Talking to your health care provider about medicines to prevent HIV:
  • PrEP is for people who don’t already have HIV but are at very high risk of getting it. PrEP is daily medicine that can reduce this risk.
  • PEP is for people who have possibly been exposed to HIV. It is only for emergency situations. PEP must be started within 72 hours after a possible exposure to HIV.

Hiv Effects On The Eyes

Some eye problems are mild, but others can be severe enough to cause blindness. Some of the most common are infections that can lead to bleeding in your retina and retinal detachment. About 7 in 10 people with untreated AIDS will have AIDS-related trouble with their eyes, usually because of cytomegalovirus.

You may not have any symptoms until the problems are far along, so if you have advanced HIV, it’s important to get regular eye exams. Call your doctor if your vision changes, including if:

  • You get blurry or double vision.
  • Colors don’t look right.

What Conditions Are Considered To Be Opportunistic

Some of the most common of these OIs/cancers among HIV-positive people include:

Cancer: The types of cancers that are you are more likely to get if you have AIDs include lymphoma, Kaposis sarcoma, invasive cervical cancer, anal cancer, liver cancer, and cancers of the mouth, throat and lungs.

Candidiasis : This condition is caused by Candida fungus. It can happen in the skin, nails and mucous membranes throughout the body, such as the mouth or the vagina. The cases can be troublesome, but thrush is especially dangerous when it affects the esophagus or parts of the respiratory system .

Pneumonia: This respiratory condition is most commonly caused by _Pneumocystis jirovecii and the bacterium Streptococcus pneumoniae._

Salmonella: This infection is spread through contaminated food and water. It causes diarrhea, vomiting and nausea.

Toxoplasmosis: This disease is caused by a parasites that live in cats and rodents and other warm-blooded animals. The infection is spread through the feces. Toxoplasmosis can cause severe problems in the lungs, heart, brain and other organs. If you have a cat, wear gloves to change the litter and be thorough in washing your hands.
