Welcome to our Guide on Depression.

By answering a series of questions, you will learn about the different forms of depression and the significance of the symptoms you or a loved one may have.

While depression comes in many forms, two features will almost always be present -- change in mood and physical changes.

Change in mood: Depression always involves a noticeable change in mood. That can mean feeling low, blue, or sad, but sometimes depression appears as irritability or not being able to enjoy everyday activities.

Physical changes: People with mood disorders may also develop changes in appetite, sleep, or energy.

The purpose of this guide is to help you better understand what depression is. This guide is not designed or intended to make a diagnosis. But knowing more about the condition often makes it easier to talk with a doctor about the symptoms you are experiencing.

Death by suicide is the most dreaded consequence of depression. Fortunately it is a rare event.

The overwhelming majority of depressed individuals do NOT commit suicide.

Thinking about suicide is a form of suffering in its own right, so mental health providers pay attention to it. They often ask questions about it in people who have symptoms of depression.

Relieving suffering from depression should reduce the risk of suicide.

The best approach to helping a person who is thinking about suicide is to treat the underlying problem or problems. But the first order of business is to make sure you stay alive to get that treatment.

Are you currently having thoughts about suicide and do you think you might act on them?

Yes, I am having thoughts about suicide.

No, I am not having thoughts about suicide.

Diaper rash, irritation of the skin in the diaper area, is one of the most common problems in newborns and infants. Almost two-thirds of children will have diaper rash at some point, and a few babies have it many times. Most cases of diaper rash disappear with simple treatments like frequent diaper changes, but some need special treatment.

Answering a few initial questions will help you learn more about common types of diaper rash and what to do for them.

• Does your child have diaper rash and fever?

• Does your child seem ill?

• Is your child's diaper rash getting worse very quickly (over a few hours)?

• Does your child have diaper rash and a rash elsewhere on the body?

Yes, my child has one or more of these symptoms.

No, my child does not have any of these symptoms.

This guide is designed to help you understand the most likely reasons for your symptoms.

If your diarrhea is substantial, if you have other unexplained symptoms such as fatigue, abdominal pain, weight loss, or blood in your bowel movements, or if your diarrhea has persisted for more than five days, you should visit with your doctor to discuss your symptoms. This guide is intended to be used as a compliment to discussions with your doctor, not as a substitute for office-based care.

You will encounter a small number of questions about your experience with diarrhea as you proceed through this program. Your answers will move you toward information that is most pertinent to your circumstances.

Because they do not share many causes in common, it is best to consider "acute" diarrhea and "chronic" diarrhea as separate symptoms.

• Acute diarrhea has an abrupt onset and replaces a previously normal bowel pattern. If you have acute diarrhea, you have probably experienced symptoms for fewer than three weeks.

• Chronic diarrhea slowly develops and persists for months or years, or it causes recurring episodes of diarrhea.

Which type of diarrhea symptoms are you experiencing?

Acute diarrhea symptoms

Chronic diarrhea symptoms

Diarrhea is loose, watery, or more frequent soft bowel movements. Common causes of diarrhea in children include infections of the stomach and intestines (gastrointestinal tract), changes in diet or anxiety. Most cases of diarrhea are not serious, go away in a day or two and can be managed at home. However, diarrhea that happens along with persistent abdominal pain, fever, vomiting, or not urinating may require a doctor's attention. Diarrhea that seems to be getting worse or that lasts more than a week also should be discussed with a doctor.

Answering the questions in this tool will help you understand more about the possible causes of diarrhea in children, and will help you decide when to call your doctor.

• decreased activity

• decreased appetite or poor feeding

Although babies often have soft stools, especially before they start eating solid foods, stools that are looser than usual, watery, or more frequent than usual are called diarrhea. Common causes of diarrhea in babies include infections of the stomach and intestines (gastrointestinal tract) or changes in diet. Most cases of diarrhea are not serious, go away in a day or two and can be managed at home. However, diarrhea that happens along with persistent abdominal pain, fever, vomiting, or not urinating may require a doctor's attention. Diarrhea that seems to be getting worse or that lasts more than one to two weeks also should be discussed with a doctor.

Answering the questions in this guide will help you understand more about the possible causes of diarrhea in babies, and will help you decide when to call your doctor.

Welcome to this Decision Guide about Difficulty Passing Urine.

Difficulty passing urine is a common problem. It can be caused by conditions that affect the kidneys, bladder or prostate gland (in men). Urinary tract infections, prostate problems, and kidney stones are common triggers for this problem to develop. In some people, more than one condition is present.

Anyone who experiences difficulty passing urine for more than 24 to 48 hours should see a doctor. This guide is intended to provide helpful information while you are awaiting evaluation for this problem, or to add to what you may have already learned after you have seen your doctor.

Please keep in mind that this information cannot replace a face-to-face evaluation with your own health care provider.

Difficulty passing urine can be triggered by different problems in men and women. Only men have a prostate gland (which can become infected or enlarged), whereas women are more prone to simple bladder infections (cystitis). Therefore, it's helpful to start by finding out if you are a woman or a man.

Are you a woman or a man?

I am a woman.

I am a man.

We're sorry you have pain!

The word "diffuse" means "widespread" and refers to pain that is more or less all over, or at least in many areas. The goal of this guide is to provide information while awaiting evaluation with your doctor, or for additional information after you have seen him or her. Please keep in mind that this guide is not intended to replace a face-to-face evaluation with your doctor. The diagnoses provided are among the most common that could explain your symptoms, but the list is not exhaustive and there are many other possibilities. In addition, more than one condition may be present at the same time. For example, a person with rheumatoid arthritis could also have tendonitis.

Please click here to begin.

Do you have severe diffuse pain with fever, redness over the skin or joints, marked swelling, inability to use the muscles or joints, or recent significant trauma (a fall, car accident, etc.)?

Yes, I have one or more of the above.

No, none of these apply to me.

Welcome to our Health Decision Guide on new onset dizziness.

Dizziness means different things to different people. To some people, dizziness means a lightheaded feeling, as though they might faint. To other people, dizziness means a feeling of imbalance, or a sensation that they are spinning or the room is spinning around them.

By answering a short series of questions, you will learn what is likely causing your type of dizziness. Please remember that the guide is not designed to substitute for consultation with a health professional.

Let's get started.

Whenever someone has dizziness, it's important to make sure there aren't additional worrisome symptoms.

If you have blacked out, fainted, or had any loss of consciousness, call your doctor immediately. Also, you can visit our guide called Fainting/Blacking Out/Loss of Consciousness.

If you feel lightheaded with standing but have not passed out or fainted, please visit our guide called Lightheaded with Standing Up.

If neither applies to you, then please continue.

Your child may experience ear pain from time to time. The pain may be caused by an ear infection, or other things, such as an injury to the ear. Children also may have other feelings in their ears. Some kids have ringing in their ears or don't hear well because of earwax in the ear canal or fluid behind the eardrum.

Answering the questions in this health decision guide will help you understand more about what usually causes children to have ear pain, and help you know what you can do for the pain and when you should contact your pediatrician for medical care. Contact your pediatrician immediately if you notice that your child is not acting well or is confused, has difficulty breathing, severe stomach pain, or a stiff neck.

Please note, this guide is not meant to take the place of a visit to your pediatrician's office.
