Whatever the cause, the consequences of being underweight can be serious. They include nutritional deficiency, fatigue, frailty, hospitalization, increased risk of falling and fall-related disabilities, slower recovery after injury, and even premature death. For these reasons, unexplained weight loss always requires a thorough medical evaluation. Snacking or eating several small meals spread throughout the day may be more effective than just 1 or 2 large meals. As often as possible, try to eat with others.
Research indicates that social isolation, including eating alone, leads to undereating.
A. Pulmonary hypertension is high blood pressure within the arteries of the lungs. Symptoms include shortness of breath on exertion, chest pain, and occasional dizziness. In the primary type, no underlying cause can be found. The secondary form is more common, especially in older adults. It is usually caused by a reduction in the amount of oxygen that reaches the air sacs owing to chronic bronchitis or emphysema.
