How Does Hiv Aids Affect The Human Body – Medical Research Cameron White, MD
HIV destroys CD4 cells, which are responsible for keeping people healthy and protecting them from disease and infection. As HIV gradually weakens the body’s natural defenses, signs and symptoms may appear.

How Does Hiv Aids Affect The Human Body
HIV usually fights a type of cell that fights off invaders like HIV. As the virus replicates, it damages or destroys infected CD4 cells, releasing more virus to infect more CD4 cells. CD4 cells are also called T cells or helper cells.

If left untreated, this cycle can continue until the immune system is severely compromised, putting the person at risk for serious illness and infection.
Acquired immunodeficiency syndrome (AIDS) is the final stage of HIV. During this stage, the immune system is greatly weakened and the risk of contracting opportunistic infections is greater.
However, not all people living with HIV will go on to develop AIDS. The sooner a person receives treatment, the better the outcome.
The immune system protects the body from disease and infection. White blood cells protect the body from viruses, bacteria, and other organisms that can make a person sick.
Hiv Aids: A Virus Master Of Evasion
A few days after being exposed to the virus, people with HIV may develop a flu-like illness that can last for several weeks. It is associated with the first stage of HIV, called acute infection or acute HIV.
HIV-positive people may not have very severe symptoms at this stage, but they often have large amounts of the virus in their blood because the virus grows rapidly.
The next stage is called the chronic infection stage. It can last 10-15 years. People infected with HIV may or may not develop symptoms during this stage.
Kaposi’s sarcoma, another complication, is a cancer of the blood vessel walls. It is rare in the general population but common in people living with HIV.
Symptoms include red or dark purple sores in the mouth and skin. It can also cause problems with the lungs, digestive tract, and other internal organs.
HIV and AIDS put people at risk for lymphoma. An early symptom of lymphoma is swollen lymph nodes.
HIV makes it more difficult to fight off respiratory illnesses like the common cold and flu. People infected with HIV may develop infections such as pneumonia.
If HIV is not treated, late-stage disease puts people with HIV at greater risk for infectious diseases, such as tuberculosis and a fungal infection called Pneumocystis jiroveci pneumonia (PJP).
How Hiv Infects A Cell
The incidence of lung cancer has also increased with HIV. This is one of many breathing problems associated with a weakened immune system in the lungs.
People living with HIV can develop high blood pressure. HIV also increases the risk of pulmonary arterial hypertension (PAH). PAH is an increase in blood pressure in the arteries that supply blood to the lungs. Over time, PAH can constrict the heart and lead to heart failure.
Tuberculosis is an airborne bacteria that affects the lungs. It is the leading cause of death among AIDS patients. Symptoms include chest pain and coughing up blood or phlegm. The cough can last for months.
Because HIV affects the immune system, it makes the body more susceptible to infections that affect the digestive system.
Signs Of Hiv To Know
Digestive tract problems can also reduce appetite, making it difficult to eat properly. Therefore, weight loss is a common feature of HIV.
A common HIV-related infection is oral thrush, a fungal infection that causes inflammation and leukoplakia on the tongue and inside the mouth.
Another viral infection that affects the mouth is oral hairy leukoplakia, which causes white lesions on the tongue.
Salmonella infection is spread through contaminated food or water and causes diarrhea, abdominal pain and vomiting. Anyone can take it
Thrush And Hiv/aids: Understanding The Link
This infection affects the bile ducts and intestines and can be particularly serious. In people with AIDS, it can cause chronic diarrhea.
Although HIV does not normally infect nerve cells, it can infect cells that protect nerves in the brain and throughout the body.
Although the link between HIV and nerve damage is not fully understood, infected supporting cells can cause nerve damage.
Late-stage HIV can cause nerve damage, also called neuropathy. This often results in pain in the legs and arms.

Small holes in the peripheral nerve fiber sheaths can cause pain, weakness, and difficulty walking. This condition is called vacuolar myelopathy.
AIDS has significant neurological complications. HIV and AIDS can cause HIV-related dementia, which severely affects cognitive function.
When the immune system is weakened, people with AIDS are at increased risk of developing inflammation of the brain and spinal cord caused by the parasite. Symptoms include confusion, headaches and seizures. Certain nervous system infections may also cause seizures.
In more severe cases, hallucinations and overt psychosis may occur. Some people may also experience headaches, balance or coordination problems, and vision problems.
What Is Hiv?
A weakened immune response can make a person more susceptible to viral infections such as herpes. Herpes can cause sores in people’s mouth or around their genitals.
HIV also increases a person’s risk of panic attacks. Reactivation of the herpes zoster virus (the virus that causes chickenpox) causes shingles. This condition is often painful and accompanied by blisters.
A viral skin infection is called molluscum contagiosum. Another condition called prurigo nodularis causes scaly patches of skin accompanied by severe itching.
HIV can cause a wide range of symptoms, from flu-like symptoms to neurological symptoms to AIDS.

Many of these effects are related to the ongoing destruction of the immune system that occurs during the development of HIV and AIDS.
However, many of these effects can be treated with antiretroviral drugs, which protect and repair the immune system.
Healthcare professionals may recommend other treatments, such as blood pressure or skin creams, to reduce the effects of HIV and AIDS on other body systems.

Hiv Transmission, Risk Factors, And Prevention
Our experts constantly monitor the health and wellness landscape and update our articles as new information becomes available. HIV progresses in three stages. The first symptoms may appear within a few weeks of contracting the virus. But in some cases, there may be no symptoms for years.
HIV is a virus that damages the immune system. There is currently no cure for HIV, but since the late 1980s, anti-HIV drug treatments have helped reduce the impact of any symptoms.
In most cases, once a person is infected with HIV, the virus remains in the body for life. However, the symptoms of HIV are different from those of other viral infections because their stages vary.
If left untreated, the disease caused by the infection occurs in three stages. Each has different potential symptoms and complications.
Hiv And Aids: The Basics
But regular antiretroviral treatment can reduce HIV in the blood to undetectable levels. This means that the virus cannot progress to the later stages of HIV infection and cannot be transmitted to a partner during sex.
The first visible stage is HIV infection. This stage is also called acute retroviral syndrome (ARS) or acute HIV infection.
It often causes flu-like symptoms, so at this stage someone may think they have a severe flu or other viral illness rather than HIV. The most common symptoms.
, the main symptoms of HIV may appear 2 to 4 weeks after first exposure. They can last several weeks. However, some people’s symptoms may last for several days.
Hiv And Aids: Medicines To Help You
ARS is common after HIV infection. But that’s not the case for everyone, as symptoms can take a decade or more to appear, according to HIV.gov.
Although the virus replicates rapidly within weeks of infection, symptoms of HIV infection do not appear until the rate of cell destruction is high.
This does not mean that people with more severe or asymptomatic HIV infection cannot spread the virus to others.
HIV infection has several stages. Early symptoms after exposure may include flu or cold symptoms. This condition can resolve on its own while HIV is still active in the body. It then develops into a chronic infection, with symptoms that can vary but include weight loss, fatigue, and unexplained injuries. The chronic phase can occur any time after the acute phase, but may not occur immediately after the acute phase. If left untreated, HIV can progress to AIDS, which is diagnosed based on the number of white blood cells circulating in the blood.
