Lightening is the settling of the fetus into the pelvis. Lay people often say, the baby has dropped. Lightening usually occurs 2 to 3 weeks before the onset of labor in primigravidas (women having their first child). During pregnancy's late stages, the uterine muscles prepare for labor and delivery by tightening and relaxing at intervals. These contractions, called Braxton-Hicks contractions, are usually painless, short, and irregular.

Acute asthma attacks generally occur when triggers or irritants (e.g., pet dander) affect the lungs. Wheezing occurs when expired air is pushed through obstructed bronchioles. Other common symptoms of asthma include difficulty breathing, chest tightness, and coughing. Pneumonia is an inflammation of the lungs, usually with consolidation and drainage. Cystic fibrosis, a multisystem chronic and incurable condition, is a major dysfunction of the exocrine glands. Some children show symptoms in infancy, including meconium ileus (causing bowel obstruction), bile-stained emesis, a distended abdomen, and no stool. Vomiting is the most common symptom of pyloric stenosis. Other symptoms include loss of weight, hunger, irritability, and dehydration.
