Losing weight when you're not trying to may sound good, but in reality it can signal a health problem. If you've lost up 10 percent of your weight during the past six months — for instance, 15 pounds (7 kilograms) if you weigh 150 pounds (68 kilograms) — see your doctor.

An unexplained drop in weight could be caused by a number of conditions, such as an overactive thyroid (hyperthyroidism), depression, liver disease, cancer or other noncancerous disorders, or disorders that interfere with how your body absorbs nutrients (malabsorption disorders).

Fever isn't an illness, but it is often a sign of one. Most of the time, a fever means your body is fighting a common viral or bacterial infection. However, a persistent low-grade fever — over 102 F (38.9 C) — that lasts for three days or more should be checked by your doctor. Similarly, if you have a high fever — greater than 104 F (40 C) — or if you're otherwise severely ill, see your doctor as soon as possible.

If you have an immune system problem or take drugs that suppress your immune system, fever may not be a reliable warning sign. Ask your primary doctor or oncologist what would signal a need for an evaluation.

Persistent fever can signal hidden infections, which could be anything from a urinary tract infection to tuberculosis. At other times, malignant conditions — such as lymphomas — cause prolonged or persistent fevers, as can some medications.

Difficulty swallowing (dysphagia) means it takes more time and effort to move food or liquid from your mouth to your stomach. Difficulty swallowing may also be associated with pain. In some cases, you may not be able to swallow at all.

Occasional difficulty swallowing usually isn't cause for concern, and may simply occur when you eat too fast or don't chew your food well enough. But persistent difficulty swallowing may indicate a serious medical condition requiring treatment.

Difficulty swallowing can occur at any age, but is more common in older adults. The causes of swallowing difficulties vary, and treatment depends on the cause.

Hemoptysis, the act of coughing up blood, is an important symptom since it frequently reflects serious underlying lung disease. Because many of the lung conditions that are heralded by hemoptysis are treatable, the symptom requires systematic and thorough evaluation to discover its etiology. A possible exception is mild hemoptysis occurring in a patient with chronic bronchitis during an acute exacerbation. Hemoptysis in this situation is common, usually mild, and self-limited. Therefore, it may be observed without further work-up. However, if the hemoptysis is substantial, persistent, or recurrent then further evaluation is indicated, particularly since patients with chronic bronchitis related to smoking are at high risk for lung cancer

A cough is the body's response to inflammation or irritation in the throat, larynx, bronchial tubes or lungs. There are two basic kinds of coughs, congested and dry, with each one having different underlying causes.
