Internal Medicine

Gastroesophageal reflux disease (GERD) occurs when stomach acid repeatedly flows back into the tube connecting your mouth and stomach (esophagus). This backwash (acid reflux) can irritate the lining of your esophagus.

Many people experience acid reflux from time to time. However, when acid reflux happens repeatedly over time, it can cause GERD.

Symptoms

Common signs and symptoms of GERD include:

• A burning sensation in your chest (heartburn), usually after eating, which might be worse at night or while lying down
• Backwash (regurgitation) of food or sour liquid
• Upper abdominal or chest pain
• Trouble swallowing (dysphagia)
• Sensation of a lump in your throat

If you have nighttime acid reflux, you might also experience:

• An ongoing cough
• Inflammation of the vocal cords (laryngitis)
• New or worsening asthma

When to see a doctor

Seek immediate medical care if you have chest pain, especially if you also have shortness of breath, or jaw or arm pain. These may be signs and symptoms of a heart attack.

An upper endoscopy, also called an upper gastrointestinal endoscopy, is a procedure used to visually examine your upper digestive system. This is done with the help of a tiny camera on the end of a long, flexible tube. A specialist uses an endoscopy to diagnose and sometimes treat conditions that affect the upper part of the digestive system.

Why it's done

An upper endoscopy is used to diagnose and sometimes treat conditions that affect the upper part of the digestive system. The upper digestive system includes the esophagus, stomach and beginning of the small intestine (duodenum).

Your provider may recommend an endoscopy procedure to:

• Investigate symptoms. An endoscopy can help determine what's causing digestive signs and symptoms, such as heartburn, nausea, vomiting, abdominal pain, difficulty swallowing and gastrointestinal bleeding.
• Diagnose. An endoscopy offers an opportunity to collect tissue samples (biopsy) to test for diseases and conditions that may be causing anemia, bleeding, inflammation or diarrhea. It can also detect some cancers of the upper digestive system.
• Treat. Special tools can be passed through the endoscope to treat problems in your digestive system. For example, an endoscopy can be used to burn a bleeding vessel to stop bleeding, widen a narrow esophagus, clip off a polyp or remove a foreign object.

Asthma is a condition in which your airways narrow and swell and may produce extra mucus. This can make breathing difficult and trigger coughing, a whistling sound (wheezing) when you breathe out and shortness of breath.

When to see a doctor

Seek emergency treatment

Severe asthma attacks can be life-threatening. Work with your doctor to determine what to do when your signs and symptoms worsen — and when you need emergency treatment. Signs of an asthma emergency include:

• Rapid worsening of shortness of breath or wheezing
• No improvement even after using a quick-relief inhaler
• Shortness of breath when you are doing minimal physical activity

An ischemic stroke occurs when the blood supply to part of the brain is interrupted or reduced, preventing brain tissue from getting oxygen and nutrients. Brain cells begin to die in minutes.

A stroke is a medical emergency, and prompt treatment is crucial. Early action can reduce brain damage and other complications.

Signs and symptoms of stroke include:

• Trouble speaking and understanding what others are saying. You may experience confusion, slur words or have difficulty understanding speech.
• Paralysis or numbness of the face, arm or leg. You may develop sudden numbness, weakness or paralysis in the face, arm or leg. This often affects just one side of the body. Try to raise both your arms over your head at the same time. If one arm begins to fall, you may be having a stroke. Also, one side of your mouth may droop when you try to smile.
• Problems seeing in one or both eyes. You may suddenly have blurred or blackened vision in one or both eyes, or you may see double.
• Headache. A sudden, severe headache, which may be accompanied by vomiting, dizziness or altered consciousness, may indicate that you're having a stroke.
• Trouble walking. You may stumble or lose your balance. You may also have sudden dizziness or a loss of coordination.

Symptoms:

The signs and symptoms of gout almost always occur suddenly, and often at night. They include:

• Intense joint pain. Gout usually affects the big toe, but it can occur in any joint. Other commonly affected joints include the ankles, knees, elbows, wrists and fingers. The pain is likely to be most severe within the first four to 12 hours after it begins.
• Lingering discomfort. 
• Inflammation and redness. The affected joint or joints become swollen, tender, warm and red.
• Limited range of motion. As gout progresses, you may not be able to move your joints normally.

When to see a doctor

If you experience sudden, intense pain in a joint, call your doctor. Gout that goes untreated can lead to worsening pain and joint damage. Seek medical care immediately if you have a fever and a joint is hot and inflamed, which can be a sign of infection.

Risk factors

You're more likely to develop gout if you have high levels of uric acid in your body. Factors that increase the uric acid level in your body include:

• Diet. Eating a diet rich in red meat and shellfish and drinking beverages sweetened with fruit sugar (fructose) increase levels of uric acid, which increase your risk of gout. Alcohol consumption, especially of beer, also increases the risk of gout.
• Weight. If you're overweight, your body produces more uric acid and your kidneys have a more difficult time eliminating uric acid.
• Medical conditions. Certain diseases and conditions increase your risk of gout. These include untreated high blood pressure and chronic conditions such as diabetes, obesity, metabolic syndrome, and heart and kidney diseases.
• Certain medications. Low-dose aspirin and some medications used to control hypertension — including thiazide diuretics, angiotensin-converting enzyme (ACE) inhibitors and beta blockers — also can increase uric acid levels. So can the use of anti-rejection drugs prescribed for people who have undergone an organ transplant.
• Family history of gout. If other members of your family have had gout, you're more likely to develop the disease.
• Age and sex. Gout occurs more often in men, primarily because women tend to have lower uric acid levels. After menopause, however, women's uric acid levels approach those of men. Men are also more likely to develop gout earlier — usually between the ages of 30 and 50 — whereas women generally develop signs and symptoms after menopause.
• Recent surgery or trauma. Experiencing recent surgery or trauma can sometimes trigger a gout attack. In some people, receiving a vaccination can trigger a gout flare.

Treatment

Gout medications are available in two types and focus on two different problems. The first type helps reduce the inflammation and pain associated with gout attacks. The second type works to prevent gout complications by lowering the amount of uric acid in your blood.

Symptoms

Acne signs vary depending on the severity of your condition:

• Whiteheads (closed plugged pores)
• Blackheads (open plugged pores)
• Small red, tender bumps (papules)
• Pimples (pustules), which are papules with pus at their tips
• Large, solid, painful lumps under the skin (nodules)
• Painful, pus-filled lumps under the skin (cystic lesions)

Acne usually appears on the face, forehead, chest, upper back and shoulders.

When to see a doctor

If self-care remedies don't clear your acne, see your primary care doctor. He or she can prescribe stronger medications. If acne persists or is severe, you may want to seek medical treatment from a doctor who specializes in the skin (dermatologist or pediatric dermatologist).
