Diseases & Conditions
The human body is a remarkable structure. It's designed to efficiently manage the wear and tear of everyday life and fend off all sorts of threats. Most of us are healthy for most of our lives. But we're also susceptible to hundreds of injuries, diseases, and conditions. Some are quite common, others are extremely rare. Here are some of the most common conditions that affect humans.

The bacteria that cause disease are remarkably resilient and can develop ways to evade the drugs meant to kill or weaken them. This phenomenon is called antibiotic resistance and it is due largely to the growing, and often careless, use of antibiotics.
Today, bacterial infections in the United States and throughout the world are becoming resistant to the drugs we rely on to treat them. Antibiotic resistance has been called one of the world's most pressing public health problems. The smart use of antibiotics is the key to controlling the spread of antibiotic resistant bacteria and the rise of superbugs—bacteria that cause infections that are difficult if not impossible to treat.
Although hard-to-read heart attacks happen to both men and women, they are more common in women. One reason for this is that men's symptoms initially set the standard for recognizing heart trouble. Now a growing body of research shows that women can experience heart attacks differently than men.
Understanding sex differences in heart disease is important. Heart disease is the leading cause of death for women. Although it mostly affects older women, it isn't rare in younger women. One in 10 of all women who die from heart disease or a stroke are under age 65, and this age group accounts for one-third of heart- or stroke-related hospitalizations. Even so, younger women and their doctors don't necessarily suspect a heart attack even when all the signs are there.
In a survey of more than 500 women who survived heart attacks, 95% of them said they noticed that something wasn't right in the month or so before their heart attacks. Two most common early warning signs were fatigue and disturbed sleep. Some women, for example, said they were so tired they couldn't make a bed without resting.
The faculty of Harvard Medical School worked with the editorial staff of Newsweek to write articles of interest about health and medicine. Harvard Medical School publishes books, newsletters, and special health reports through its Harvard Health Publishing division.

Interstitial cystitis is a chronic inflammation of the bladder that causes people to urinate -- sometimes painfully -- as often as 40, 50, or 60 times a day. Their quality of life, research suggests, resembles that of a person on kidney dialysis or suffering from chronic cancer pain. Not surprisingly, the condition is officially recognized as a disability.
There's no cure for interstitial cystitis, but many treatments offer some relief, either on their own or in combination.
Treatment (see chart) is aimed at relieving pain and reducing inflammation. The two main approaches are oral medications and bladder instillations -- drugs that are introduced into the bladder by catheter and held for 15 minutes. The procedure usually takes place in a physician's office, but in some cases these drugs can be self-administered at home.
"Stay away from me! I don't want to get sick, too." Most of us have had to utter those words to a family member, friend, or colleague who was sneezing or coughing incessantly. But how do we know how great the chances of catching someone's cold or other illness really are? A medical review published in the New England Journal of Medicine tells us when to exercise concern over eight respiratory tract infections.
