To determine the cause of your wheezing, your doctor will ask questions about your symptoms and what triggers them. For example, if you have no history of lung disease and you always wheeze after eating a certain food or at a certain time of year, the doctor may suspect that you have a food or respiratory allergy.

Sickle cell disease changes the shape of the oxygen-carrying molecules (called hemoglobin) found inside red blood cells. Red blood cells are usually round and flexible. This allows them to glide smoothly through your bloodstream. But when you have sickle cell disease, the abnormal hemoglobin creates stiff, sickle-shaped red blood cells.

Urticaria pigmentosa — also known as maculopapular cutaneous mastocytosis (MPCM) — is an itchy rash that shows up most often in children and young adults. The rash may look reddish-brown, gray, purplish, or tan, depending on your skin tone. It may turn into hives or blisters when you rub or scratch it. This reaction is called Darier’s sign.

Prostate cancer happens when a tumor grows in the prostate gland, which makes the liquid portion of semen. Cancer that spreads outside the prostate gland to the lymph nodes, bones, or other areas is called metastatic prostate cancer. Currently, no treatments can cure advanced prostate cancer. But there are ways to help control its spread and related symptoms.

Usually, your uterus tips forward at the cervix (a cylinder-shaped neck of tissue that connects the vagina and uterus). A tilted or tipped uterus tips backward instead of forward. It’s a fairly common difference in how a uterus is positioned.

The key treatments for asthma are steroids and other anti-inflammatory drugs. These asthma drugs both help to control asthma and prevent asthma attacks.

Steroids and other anti-inflammatory drugs work by reducing inflammation, swelling, and mucus in the airways of a person with asthma. As a result, the airways are less inflamed and less likely to react to asthma triggers, allowing people with symptoms of asthma to have better control over their condition.

If you or a loved one has asthma, you should know about the best treatments for short-term relief and long-term control. This will help you and your doctor manage the symptoms. If you have symptoms or an asthma attack, it’s important to know when to call your doctor to prevent an emergency.

Orexins are chemicals in your brain that help your body stay awake. Orexins also make sure that rapid-eye movement (REM) sleep — sleep with intense dreams that happens about an hour after you fall asleep — doesn’t happen at the wrong times.

You might also hear orexins called hypocretins, but they’re the same thing.

If you’re thinking about using emergency contraception, you may wonder: What will I feel like afterward?

The pill forms are safe. That’s why you can buy some of them without a prescription. They have the same hormones that are in birth control pills, which people have been using for decades. The copper-T IUD (intrauterine device) is also a very effective, safe way to prevent a pregnancy after sex.

You have a lot of choices for birth control, from condoms to caps to pills. Find one that you’re confident with — and that you can commit to using every time you have sex.

Sickle cell disease (SCD) is the most common inherited blood disorder. That means it’s passed down through families. You’re born with SCD. It’s not something you catch or develop later in life.

A traumatic brain injury (TBI) is an injury to your brain, often caused by a blow to the head. TBIs can damage nerve cells and cause bleeding or swelling in your brain.

Most TBIs are treatable, but they can affect your daily life and cause you physical, mental, or emotional stress.

After remission from an acute episode of mania or depression, people with bipolar disorder are at an especially high risk of relapse for about six months. So, continuation and maintenance of (ongoing) therapy is often recommended as treatment.

Breast cancer treatments are getting better all the time, and people have many more options today than ever. With so many choices, it’s a good idea to learn as much as you can about the ones that can help you the most.

Attention deficit hyperactivity disorder (ADHD) is often thought of as a "boys' disorder" because it's nearly twice as common in boys as girls. But it's important to note that ADHD can look different in girls. That's because of the different ways girls' and boys' brains develop and where their focuses lie.

Treatment for bipolar disorder has come a long way. Today, mood stabilizing drugs are a mainstay treatment for bipolar disorder. Doctors may prescribe lithium, an antimanic drug, or an antipsychotic drug — or a combination of both — in order to alleviate symptoms of depression without triggering a manic episode.

Antipsychotic medications are used as short or long-term treatments for bipolar disorder to control psychotic symptoms such as hallucinations, delusions, or mania symptoms. These symptoms may show up during acute mania or severe depression episodes. Some also treat depression, and several have demonstrated long-term value in preventing future episodes of mania or depression.

Bipolar disorder and ADHD, or attention deficit hyperactivity disorder, are two conditions that are diagnosed more and more in American children and teens — often at the same time.

If you find yourself getting stressed at work, know that it happens to everyone and it’s completely normal. But if you realize that stress is constant, overwhelming, and prevents you from living your life, it could be an anxiety disorder.

Having anxiety at work can have a huge impact on you and your career. People who feel anxious at work might even make career decisions based on their anxiety.

You can live a full, active life when you have sickle cell disease. Making smart choices is important in keeping the condition from flaring into a crisis.

Sickle cell disease (SCD) is an inherited disorder in which the shape of red blood cells are C-shaped sickles that can get stuck in blood vessels and block them. This blockage is called a pain crisis or sickle crisis.
