One symptom often triggers the other. Fortunately, abdominal bloating and nausea usually resolve themselves with time. Examples of conditions that cause abdominal bloating and nausea include: 1  acid reflux. 2  constipation. 3  gastroesophageal reflux disease (GERD). 4  gastrointestinal blockage. 5  gastroparesis. 6  giardiasis (an infection from an intestinal parasite).
Puberty is the process of physical changes through which a child's body matures into an adult body capable of sexual reproduction. It is initiated by hormonal signals from the brain to the gonads: the ovaries in a girl, the testes in a boy.
General habitus and shape of body and face, as well as sex hormone levels, are similar in prepubertal boys and girls. As puberty progresses and sex hormone levels rise, differences appear, though puberty causes some similar changes in male and female bodies.eneral habitus and shape of body and face, as well as sex hormone levels, are similar in prepubertal boys and girls.
