You may have heard of anabolic steroids, which can have harmful effects. But there's another type of steroid - sometimes called a corticosteroid - that treats a variety of problems. These steroids are similar to hormones that your adrenal glands make to fight stress associated with illnesses and injuries. They reduce inflammation and affect the immune system.
You may need to take corticosteroids to treat:
Steroids are strong medicines, and they can have side effects, including weakened bones and cataracts. Because of this, you usually take them for as short a time as possible.
Anabolic steroids are synthetic (man-made) versions of testosterone. Testosterone is the main sex hormone in men. It is needed to develop and maintain male sex characteristics, such as facial hair, deep voice, and muscle growth. Women do have some testosterone in their bodies, but in much smaller amounts.
What are anabolic steroids used for?Health care providers use anabolic steroids to treat some hormone problems in men, delayed puberty, and muscle loss from some diseases. But some people misuse anabolic steroids by taking them in a way that's different than their provider prescribed.
Why do people misuse anabolic steroids?Some bodybuilders and athletes use anabolic steroids to build muscles and improve athletic performance. They may take steroids by swallowing tablets or capsules, inject them into muscles, or apply them to the skin as a gel or cream. These doses may be 10 to 100 times higher than doses used to treat medical conditions. Using them this way, without a prescription from a provider, is not legal or safe.
What are the health effects of misusing anabolic steroids?Misuse of anabolic steroids, especially over a long period of time, has been linked with many health problems, including:
In men, it can also cause:
In women, it can also cause:
Even though they don't cause a high, anabolic steroids can lead to addiction. You can have withdrawal symptoms if you stop using them, including:
Behavioral therapy and medicines can be helpful in treating anabolic steroid addiction

Eosinophilic esophagitis (EoE) is a chronic disease of the esophagus. Your esophagus is the muscular tube that carries food and liquids from your mouth to the stomach. If you have EoE, white blood cells called eosinophils build up in your esophagus. This causes damage and inflammation, which can cause pain, trouble swallowing, and food getting stuck in your throat.
EoE is rare. But because it is a newly recognized disease, it is being diagnosed more often. Some people who think that they have reflux (GERD) may actually have EoE.
What causes eosinophilic esophagitis (EoE)?Researchers are not certain about the exact cause of EoE. They think that it is an immune system/allergic reaction to foods or to substances in your environment, such as dust mites, animal dander, pollen, and molds. Certain genes may also play a role in EoE.
Who is at risk for eosinophilic esophagitis(EoE)?EoE can affect anyone, but it is more common in people who:
The most common symptoms of EoE can depend on your age.
In infants and toddlers::
In older children::
In adults::
To find out if you have EoE, your doctor will likely:
There is no cure for EoE. Treatments can manage your symptoms and prevent further damage. The two main types of treatments are medicines and diet.
Medicines used to treat EoE are:
Dietary changes for EoE include:
Which treatment your doctor suggests depends on different factors, including your age. Some people may use more than one kind of treatment. Researchers are still trying to understand EoE and how best to treat it.
If your treatment is not working well enough and you have narrowing of the esophagus, you may need dilation. This is a procedure to stretch the esophagus. This makes it easier for you to swallow.
Your adrenal glands are two small organs that sit on top of each kidney. The adrenal glands make different types of hormones you need to stay alive and healthy. Hormones are chemicals that travel in your bloodstream and control how different parts of your body work.
The adrenal glands make the hormones cortisol, aldosterone, adrenaline, and noradrenaline. They also make hormones that your body uses to make sex hormones (estrogen and testosterone). All of these hormones do many important jobs, including:
When you have an adrenal gland disorder, your body makes too much or too little of one or more hormones. The symptoms depend on the type of problem you have and how much it affects the hormone levels in your body.
There are many types of adrenal gland disorders, including:
The cause of adrenal gland disorders depends on the type of disorder you have. Causes can include:
In many cases the cause of the problem isn't clear.
How are adrenal gland disorders diagnosed?Health care providers use different tests to check for adrenal disorders depending on your symptoms and health history. For example, you may have tests of your blood, urine (pee), or saliva (spit). These tests check your hormone levels. Your provider may order x-rays, CT scans, or MRI scans to look for tumors.
What are the treatments for adrenal gland disorders?Different types of adrenal gland disorders have different treatments. They include medicines and surgery. Radiation therapy is sometimes a treatment for tumors. There are treatments to cure certain adrenal gland disorders. For other disorders, treatments can manage your symptoms.

Aspergillosis is a disease caused by a fungus (or mold) called Aspergillus. The fungus is very common in both indoors and outdoors. Most people breathe in the spores of the fungus every day without being affected. But some people get the disease. It usually occurs in people with lung diseases or weakened immune systems.
There are different kinds of aspergillosis. One kind is allergic bronchopulmonary aspergillosis (also called ABPA). Symptoms of ABPA include wheezing and coughing. ABPA can affect healthy people but it is most common in people with asthma or cystic fibrosis.
Another kind is invasive aspergillosis, which damages tissues in the body. It usually affects the lungs. Sometimes it can also cause infection in other organs and spread throughout the body. It affects people who have immune system problems, such as people who have had a transplant, are taking high doses of steroids, or getting chemotherapy for some cancers.
Your doctor might do a variety of tests to make the diagnosis, including a chest x-ray, CT scan of the lungs, and an examination of tissues for signs of the fungus. Treatment is with antifungal drugs. If you have ABPA, you may also take steroids.

Drug use, or misuse, includes:
Young people's brains are growing and developing until they are their mid-20's. This is especially true of the prefrontal cortex, which is used to make decisions. Taking drugs when young can interfere with developmental processes occurring in the brain. It can also affect their decision-making. They may be more likely to do risky things, such as unsafe sex and dangerous driving.
The earlier young people start using drugs, the greater their chances of continuing to use them and become addicted later in life.Taking drugs when you are young can contribute to the development of adult health problems, such as heart disease, high blood pressure, and sleep disorders.
Which drugs most commonly used by young people?The drugs that are most commonly used by young people are alcohol, tobacco, and marijuana. Recently, more young people have started vaping tobacco and marijuana. There is still a lot we don't know about the dangers of vaping. Some people have unexpectedly gotten very ill or have even died after vaping. Because of this, young people should stay away from vaping.
Why do young people take drugs?There are many different reasons why a young person may take drugs, including:
Different factors may raise a young person's risk for drug use, including:
Drug use and addiction are preventable. Prevention programs involving families, schools, communities, and the media may prevent or reduce drug use and addiction. These programs include education and outreach to help people understand the risks of drug use.

Asthma is a chronic (long-term) lung disease. It affects your airways, the tubes that carry air in and out of your lungs. When you have asthma, your airways can become inflamed and narrowed. This can cause wheezing, coughing, and tightness in your chest. When these symptoms get worse than usual, it is called an asthma attack or flare-up.
What causes asthma?The exact cause of asthma is unknown. Genetics and your environment likely play a role in who gets asthma.
An asthma attack can happen when you are exposed to an asthma trigger. An asthma trigger is something that can set off or worsen your asthma symptoms. Different triggers can cause different types of asthma:
Asthma triggers may be different for each person and can change over time.
Who is at risk for asthma?Asthma affects people of all ages, but it often starts during childhood. Certain factors can raise your risk of having asthma:
The symptoms of asthma include:
These symptoms can range from mild to severe. You may have them every day or only once in a while.
When you are having an asthma attack, your symptoms get much worse. The attacks may come on gradually or suddenly. Sometimes they can be life-threatening. They are more common in people who have severe asthma. If you are having asthma attacks, you may need a change in your treatment.
How is asthma diagnosed?Your health care provider may use many tools to diagnose asthma:
If you have asthma, you will work with your health care provider to create a treatment plan. The plan will include ways to manage your asthma symptoms and prevent asthma attacks. It will include:
If you have a severe attack and the short-term relief medicines do not work, you will need emergency care.
Your provider may adjust your treatment until asthma symptoms are controlled.
Sometimes asthma is severe and cannot be controlled with other treatments. If you are an adult with uncontrolled asthma, in some cases your provider might suggest bronchial thermoplasty. This is a procedure that uses heat to shrink the smooth muscle in the lungs. Shrinking the muscle reduces your airway's ability to tighten and allows you to breathe more easily. The procedure has some risks, so it's important to discuss them with your provider.
A brain tumor is a growth of abnormal cells in the tissues of the brain. Brain tumors can be benign, with no cancer cells, or malignant, with cancer cells that grow quickly. Some are primary brain tumors, which start in the brain. Others are metastatic, and they start somewhere else in the body and move to the brain.
Brain tumors can cause many symptoms. Some of the most common are:
Doctors diagnose brain tumors by doing a neurologic exam and tests including an MRI, CT scan, and biopsy. Treatment options include watchful waiting, surgery, radiation therapy, chemotherapy, and targeted therapy. Targeted therapy uses drugs or other substances that attack cancer cells with less harm to normal cells. Many people get a combination of treatments.

Cancer is a group of related diseases. In all types of cancer, some of the body's cells begin to divide without stopping and spread into surrounding tissues.
Normally, new cells form as you need them, replacing old cells that die. Sometimes, this process goes wrong. New cells form when you don't need them, and old cells don't die when they should. The extra cells can form a tumor. Tumors can be benign or malignant. Benign tumors aren't cancer. Malignant tumors are cancer, and the cancer cells can spread to nearby tissues. They can also break away and spread to other parts of the body.
Children can get cancer in the same parts of the body as adults, but there are differences. Childhood cancers may happen suddenly, without early symptoms. Some types can often be cured. The most common children's cancer is leukemia. Some of the other more common types of cancer in children include brain tumors, lymphoma, and soft tissue sarcoma.
Symptoms and treatment depend on the type of cancer and how advanced it is. Treatments may include:

A cataract is a clouding of the clear lens inside your eye. This cloudiness blocks light from reaching the back of the eye, making it harder to see clearly. A cataract can affect one or both eyes, but it doesn't spread from one eye to the other.
Cataracts usually develop slowly. As they get worse, your vision can become blurry or dim. Brighter lighting or new eyeglasses may help at first, but if cataracts begin to interfere with your daily activities, you may need cataract surgery.
Without treatment, cataracts can cause severe or even permanent loss of vision.
What causes cataracts?Most cataracts develop as part of the normal aging process. This happens when the protein in the lens of your eye clumps together. Over time, these protein clumps grow larger and thicker, making it harder to see. The lens may turn yellow or brown, which can affect how you see colors.
Cataracts can also develop after an eye injury or surgery for another eye condition, like glaucoma.
Who is more likely to develop cataracts?Cataracts are very common in older adults. By age 80, more than half of all Americans either have a cataract or have had cataract surgery. Your risk for developing cataracts increases as you get older. You may also be at an increased risk if you:
You may not notice cataracts at first because they usually develop slowly. That's why regular eye exams are important. Common symptoms may include:
Talk with your provider about these symptoms since they could also be signs of other eye problems.
How are cataracts diagnosed?A comprehensive eye exam is the best way to check for cataracts. Your provider will do several tests to check your vision and eye health. This includes a dilated eye exam, where your pupils are widened with special eye drops. This allows more light to enter your eye so your provider can clearly see tissues at the back.
How are cataracts treated?Surgery is the only way to remove a cataract. At first, you may be able to improve your vision with new glasses and brighter lighting. But if cataracts are getting in the way of everyday activities like reading, driving, or watching TV, surgery is an option. During surgery, the cloudy lens is removed and replaced with an artificial lens, called an intraocular lens (IOL).
Can cataracts be prevented?If you're worried that you're at risk for cataracts, talk to your provider to see if there's anything you can do to lower your risk. A few ways to protect your eyes include:
