Caesarean section, also known as C-section, or caesarean delivery, is the use of surgery to deliver babies. A caesarean section is often necessary when a vaginal delivery would put the baby or mother at risk. This may include obstructed labor, twin pregnancy, high blood pressure in the mother, breech birth, or problems with the placenta or umbilical cord. A caesarean delivery may be performed based upon the shape of the mother's pelvis or history of a previous C-section. A trial of vaginal birth after C-section may be possible. The World Health Organization recommends that caesarean section be performed only when medically necessary. C-sections are performed without a medical reason, upon request by someone, usually the mother. - Wikipedia
Sinus infections happen when fluid builds up in the air-filled pockets in the face (sinuses), which allows germs to grow. Viruses cause most sinus infections, but bacteria can cause some sinus infections.
