Blue Color (cyanosis)

A blue color of the skin means lack of oxygen in the tissues. Lack of oxygen (called hypoxia) can occur for a variety of reasons, including lung problems, heart problems or circulation problems. When hypoxia is moderately severe, blue color can be limited to the lips, the fingers and toes. Severe hypoxia causes a blue or gray color to appear over the entire body. Cyanosis should always lean to an evaluation by a doctor and often means an emergency situation.

Dizziness

Dizziness can mean several things to people. Some refer to a light-headed or “fuzzy” feeling as dizziness, while others mean a feeling of spinning or reeling (which is more properly called vertigo). Light-headedness or giddiness often results from a decrease of blood flow to the brain. Vertigo, on the other hand, originates in the inner ear, which controls balance.

Heart Rate Changes

The sensation of changing or irregular heartbeat is very bothersome for people, especially if they have or think they have heart disease. Palpitations are the sensations of the heart skipping a beat, beating irregularly or pounding in the chest.

Most people have changes in the heart rate and rhythm as part of a normal day and palpitations may signal no disease at all. Others have this as a sign of heart disease. When palpitations are pronounced, or frequent, or if they are associated with symptoms of light-headedness or difficulty in breathing – seek medical care.
