Hypoventilation may be caused by an uneven distribution of inspired air (as in bronchitis), obesity, neuromuscular or skeletal disease affecting the thorax, decreased response of the respiratory center to carbon dioxide, or a reduced amount of functional lung tissue, as in atelectasis, emphysema, and pleural effusion.
Seborrheic Keratosis Causes Wart Like Skin Growths. Seborrheic keratosis causes wart like skin growths to appear on just about every body thatâs over age 40. Although they resemble skin cancer, these keratosis tumors are benign.
Warts can also cause the skin to lose its pigment and become discolored. The wart itself can have a different color than the rest of the skin but the area around it can be affected as well. The growths are typically the same color as the skin but they can also become grey or a darker color.
