Many men develop urinary problems as they get older. They might find it hard to urinate, have a strong and sudden urge to “go,” be unable to hold it in, or wake up often at night to urinate.

Risks are all around us. A nearby sneeze may raise your risk for catching the flu. Obesity boosts the odds you’ll get diabetes. Smoking increases your risk for many cancers.

Pneumonia can be very serious and even life-threatening. Vaccines can help prevent some types of pneumonia. Good hygiene (washing your hands often), quitting smoking, and keeping your immune system strong by getting regular physical activity and eating healthy are other ways to lower your risk of getting pneumonia.

Your doctor will diagnose pneumonia based on your medical history, a physical exam, and test results. Sometimes pneumonia is hard to diagnose because your symptoms may be the same as a cold or flu. You may not realize that your condition is more serious until it lasts longer than these other conditions.

The signs and symptoms of pneumonia can be mild or serious. Young children, older adults, and people who have serious health conditions are at risk for developing more serious pneumonia or life-threatening complications.

Your risk of pneumonia may be higher because of your age, environment, lifestyle habits, and other medical conditions.

Pneumonia occurs when certain bacterial, viral, and fungal infections cause inflammation in the air sacs, or alveoli, of the lungs.

A harmful algal bloom (HAB) occurs when toxin-producing algae grow excessively in a body of water. Algae are microscopic organisms that live in aquatic environments and use photosynthesis to produce energy from sunlight, just like plants. The excessive algal growth, or algal bloom, becomes visible to the naked eye and can be green, blue-green, red, or brown, depending on the type of algae.
