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.
Similar patterns were evident for behavior difficulties, but only for boys; early puberty was not related to behavior difficulties in girls. CONCLUSIONS: Children with early puberty have different patterns of behavior and social adjustment from the preschool years through early adolescence.At least in part, the association between early-onset puberty and poor mental health appears to result from processes under way well before the onset of puberty.ONCLUSIONS: Children with early puberty have different patterns of behavior and social adjustment from the preschool years through early adolescence.
