What Causes Purple Lips

Although there are many possible answers behind what causes purple lips, the medical condition cyanosis is the prime underlying suspect.

Blue lips are common in infants and the elderly.

When temperatures start to fall, many people wonder what causes purple lips. Purple lips can accompany cold weather, but they can also indicate underlying medical conditions, some that require prompt treatment. Here's a look at some of the common causes of purple lips.

These conditions may be to blame for purple lips:

• Lack of oxygen
• Poor circulation
• Cyanosis
• Cold temperatures

Cyanosis is a medical condition that causes discoloration and bluing of the skin and membranes. Linked to lack of oxygen, cyanosis may be attributed to underlying lung or breathing problems. Often seen in infants with birth defects or lung problems, cyanosis also affects the elderly.

The first physical symptom of cyanosis is a bluish cast on the fingernails, lips, capillaries, veins and tongue. Cyanosis, in many cases, is linked to a serious underlying disease.

The following serious diseases or conditions may be causing cyanosis, or bluing of the lips:

• Heat disease
• Heart failure
• Lung disease
• Myocardial infarction
• Pulmonary embolism
• Chronic bronchitis
• Asthma
• Abnormal hemoglobin levels
• Heart valve disease
• Hypoventilation

Unless the cause of bluing lips can be attributed to cold or frigid temperatures, it is important to seek immediate medical attention and diagnosis to rule out any of these serious conditions.

For those venturing out into extreme and cold temperatures, proper precautions should always be made to avoid serious conditions, such as hypothermia.

The following winter care tips are recommended for protection and safety:

• Dress warmly, and in layers. Because the body's internal temperature fluctuates in extreme conditions, it is always best to dress in layers. If you are active in frigid temps, you can easily work up a sweat. Moisture wicking thermal fabrics will help moderate body temps, avoiding the risk of overheating.
• Sunscreen: Sunscreen is a crucial, often overlooked product that should always be part of cold weather skincare. For those skiing on the slopes, sunblock will prevent the burn associated with intensive sun rays.
• Hats and gloves: Protect your extremities and regulate internal temperatures by wearing hats and gloves. Look for wool or lightweight fleece fibers.
• Take breaks: To avoid any serious medical conditions, take breaks while working or playing outdoors. Your body is working hard to stay warm and dry, so give it time to recoup.
• Stay hydrated: Although you may not feel thirst is extreme cold temperatures, staying hydrated is vital to keep your internal organs functioning properly.
• Lip balm: To keep lips hydrated and supple, reapply a lip balm with an SPF as often as needed.

Although the many underlying medical conditions of blue lips can be worrisome, prompt treatment always ensures the most positive outlook. If you are experiencing blue lips, seek attention to rule out or treat any underlying, serious diseases as soon as possible.
