Candida is the scientific name for yeast. It is a fungus that lives almost everywhere, including in your body. Usually, your immune system keeps yeast under control. If you are sick or taking antibiotics, it can multiply and cause an infection.
Yeast infections affect different parts of the body in different ways:
Antifungal medicines get rid of yeast infections in most people. If you have a weak immune system, treatment might be more difficult.
Vaginitis, also called vulvovaginitis, is an inflammation or infection of the vagina. It can also affect the vulva, which is the external part of a woman's genitals. Vaginitis can cause itching, pain, discharge, and odor.
Vaginitis is common, especially in women in their reproductive years. It usually happens when there is a change in the balance of bacteria or yeast that are normally found in your vagina. There are different types of vaginitis, and they have different causes, symptoms, and treatments.
What causes vaginitis?Bacterial vaginosis (BV) is the most common vaginal infection in women ages 15-44. It happens when there is an imbalance between the "good" and "harmful" bacteria that are normally found in a woman's vagina. Many things can change the balance of bacteria, including:
Yeast infections (candidiasis) happen when too much candida grows in the vagina. Candida is the scientific name for yeast. It is a fungus that lives almost everywhere, including in your body. You may have too much growing in the vagina because of:
Trichomoniasis can also cause vaginitis. Trichomoniasis is a common sexually transmitted disease. It is caused by a parasite.
You can also have vaginitis if you are allergic or sensitive to certain products that you use. Examples include vaginal sprays, douches, spermicides, soaps, detergents, or fabric softeners. They can cause burning, itching, and discharge.
Hormonal changes can also cause vaginal irritation. Examples are when you are pregnant or breastfeeding, or when you have gone through menopause.
Sometimes you can have more than one cause of vaginitis at the same time.
What are the symptoms of vaginitis?The symptoms of vaginitis depend on which type you have.
With BV, you may not have symptoms. You could have a thin white or gray vaginal discharge. There may be an odor, such as a strong fish-like odor, especially after sex.
Yeast infections produce a thick, white discharge from the vagina that can look like cottage cheese. The discharge can be watery and often has no smell. Yeast infections usually cause the vagina and vulva to become itchy and red.
You may not have symptoms when you have trichomoniasis. If you do have them, they include itching, burning, and soreness of the vagina and vulva. You may have burning during urination. You could also have gray-green discharge, which may smell bad.
How is the cause of vaginitis diagnosed?To find out the cause of your symptoms, your health care provider may:
In some cases, you may need more tests.
What are the treatments for vaginitis?The treatment depends on which type of vaginitis you have.
BV is treatable with antibiotics. You may get pills to swallow, or cream or gel that you put in your vagina. During treatment, you should use a condom during sex or not have sex at all.
Yeast infections are usually treated with a cream or with medicine that you put inside your vagina. You can buy over-the-counter treatments for yeast infections, but you need to be sure that you do have a yeast infection and not another type of vaginitis. See your health care provider if this is the first time you have had symptoms. Even if you have had yeast infections before, it is a good idea to call your health care provider before using an over-the-counter treatment.
The treatment for trichomoniasis is usually a single-dose antibiotic. Both you and your partner(s) should be treated, to prevent spreading the infection to others and to keep from getting it again.
If your vaginitis is due to an allergy or sensitivity to a product, you need to figure out which product is causing the problem. It could be a product that you started using recently. Once you figure it out, you should stop using the product.
If the cause of your vaginitis is a hormonal change, your health care provider may give you estrogen cream to help with your symptoms.
Can vaginitis cause other health problems?It is important to treat BV and trichomoniasis, because having either of them can increase your risk for getting HIV or another sexually transmitted disease. If you are pregnant, BV or trichomoniasis can increase your risk for preterm labor and preterm birth.
Can vaginitis be prevented?To help prevent vaginitis:
Your mouth is one of the most important parts of your body. It has many different functions. It allows you to:
Any problem that affects your mouth can make it hard to eat, drink, or even smile. Some common mouth problems include:
Treatment for mouth disorders varies, depending on the problem. If a mouth problem is caused by some other disease, treating that disease can help. It is also important to keep your mouth clean and healthy by brushing, flossing, and not using tobacco.
During pregnancy, some common infections like the common cold or a skin infection do not usually cause serious problems. But other infections can be dangerous to you, your baby, or both. Some infections may lead to preterm birth and low birth weight babies. Others can cause serious illness, birth defects, and lifelong disabilities, such as hearing loss or learning problems.
Some of the infections that can be dangerous during pregnancy include:
To try to prevent infections,:
If you do get an infection during pregnancy, contact your health care provider about how best to protect you and your baby. Only some medicines are safe during pregnancy.
Antibiotics are medicines that fight bacterial infections in people and animals. They work by killing the bacteria or by making it hard for the bacteria to grow and multiply.
Antibiotics can be taken in different ways:
Antibiotics only treat certain bacterial infections, such as strep throat, urinary tract infections, and E. coli.
You may not need to take antibiotics for some bacterial infections. For example, you might not need them for many sinus infections or some ear infections. Taking antibiotics when they're not needed won't help you, and they can have side effects. Your health care provider can decide the best treatment for you when you're sick. Don't ask your provider to prescribe an antibiotic for you.
Do antibiotics treat viral infections?Antibiotics do not work on viral infections. For example, you shouldn't take antibiotics for:
The side effects of antibiotics range from minor to very severe. Some of the common side effects include:
More serious side effects can include:
Call your health care provider if you develop any side effects while taking your antibiotic.
Why is it important to take antibiotics only when they're needed?You should only take antibiotics when they are needed because they can cause side effects and can contribute to antibiotic resistance. Antibiotic resistance happens when the bacteria change and become able to resist the effects of an antibiotic. This means that the bacteria continue to grow.
How do I use antibiotics correctly?When you take antibiotics, it is important that you take them responsibly:

Your immune system protects you from disease and infection by attacking germs that get into your body, such as viruses and bacteria. Your immune system can tell that the germs aren't part of you, so it destroys them. If you have an autoimmune disease, your immune system attacks the healthy cells of your organs and tissues by mistake.
There are more than 80 types of autoimmune diseases. They can affect almost any part of your body. For example, alopecia areata is an autoimmune disease of the skin that causes hair loss. Autoimmune hepatitis affects the liver. In type 1 diabetes, the immune system attacks the pancreas. And in rheumatoid arthritis, the immune system can attack many parts of the body, including the joints, lungs, and eyes.
What causes autoimmune diseases?No one is sure why autoimmune diseases happen. But you can't catch them from other people.
Autoimmune diseases do tend to run in families, which means that certain genes may make some people more likely to develop a problem. Viruses, certain chemicals, and other things in the environment may trigger an autoimmune disease if you already have the genes for it.
Who is at risk for autoimmune diseases?Millions of Americans of all ages have autoimmune diseases. Women develop many types of autoimmune diseases much more often than men. And if you have one autoimmune disease, you are more likely to get another.
What are the symptoms of autoimmune diseases?The symptoms of an autoimmune disease depend on the part of your body that's affected. Many types of autoimmune diseases cause redness, swelling, heat, and pain, which are the signs and symptoms of inflammation. But other illnesses can cause the same symptoms.
The symptoms of autoimmune diseases can come and go. During a flare-up, your symptoms may get severe for a while. Later on, you may have a remission, which means that your symptoms get better or disappear for a period of time.
How are autoimmune diseases diagnosed?Doctors often have a hard time diagnosing autoimmune diseases. There's usually not a specific test to show whether you have a certain autoimmune disease. And the symptoms can be confusing. That's because many autoimmune diseases have similar symptoms. And some symptoms, such as muscle aches, are common in many other illnesses. So it can take a long time and some visits to different types of doctors to get a diagnosis.
To help your doctor find out if an autoimmune disease is causing your symptoms,:
The treatment depends on the disease. In most cases, the goal of treatment is to suppress (slow down) your immune system, and ease swelling, redness, and pain from inflammation. Your doctor may give you corticosteroids or other medicines to help you feel better. For some diseases, you may need treatment for the rest of your life.
It is hard when your baby is sick. Common health problems in babies include colds, coughs, fevers, and vomiting. Babies also commonly have skin problems, like diaper rash or cradle cap.
Many of these problems are not serious. It is important to know how to help your sick baby, and to know the warning signs for more serious problems. Trust your intuition - if you are worried about your baby, call your health care provider right away.
Your endocrine system includes eight major glands throughout your body. These glands make hormones. Hormones are chemical messengers. They travel through your bloodstream to tissues or organs. Hormones work slowly and affect body processes from head to toe. These include:
If your hormone levels are too high or too low, you may have a hormone disorder. Hormone diseases also occur if your body does not respond to hormones the way it is supposed to. Stress, infection and changes in your blood's fluid and electrolyte balance can also influence hormone levels.
In the United States, the most common endocrine disease is diabetes. There are many others. They are usually treated by controlling how much hormone your body makes. Hormone supplements can help if the problem is too little of a hormone.
If you have ever had athlete's foot or a yeast infection, you can blame a fungus. A fungus is a primitive organism. Mushrooms, mold and mildew are examples. Fungi live in air, in soil, on plants and in water. Some live in the human body. Only about half of all types of fungi are harmful.
Some fungi reproduce through tiny spores in the air. You can inhale the spores or they can land on you. As a result, fungal infections often start in the lungs or on the skin. You are more likely to get a fungal infection if you have a weakened immune system or take antibiotics.
Fungi can be difficult to kill. For skin and nail infections, you can apply medicine directly to the infected area. Oral antifungal medicines are also available for serious infections.
Having HIV/AIDS weakens your body's immune system. It destroys the white blood cells that fight infection. This puts you at risk for opportunistic infections (OIs). OIs are serious infections that take advantage of your weak immune system. These infections are less common and less severe in healthy people.
There are many types of OIs:
Having HIV/AIDS can make infections harder to treat. People with HIV/AIDS are also more likely to have complications from common illnesses such as the flu.
You can help prevent infections by taking your HIV/AIDS medicines. Other things that can help include practicing safe sex, washing your hands well and often, and cooking your food thoroughly.
