What Is Histamine? Histamine is an important part of your bodyâs immune response, but high levels of the chemical compound can cause health problems. Histamine is a chemical produced in cells throughout the body as part of the bodyâs inflammatory response to allergy, infection, or injury. When damaged or exposed to allergens, cells in the skin, nose, throat and lungs release histamine, resulting in pain, itchiness, redness, runny nose, and wheezing.

Birth is considered premature, or preterm, when it occurs before 37 weeks of gestation (development time in the womb). Normal, full-term gestation is 37 to 42 weeks. Those final weeks in the womb are crucial for healthy weight gain and development of the babyâs vital organs. Late preterm babies (born at 35 to 37 weeks gestation) may look fully mature, but they still have greater risks of health problems than babies born full term.
