Study design
At the time of recruitment, each patient will perform an initial clinical nutrition examination, during which will be evaluated, on the basis of BMI and specific anthropometric parameters, the necessary nutritional intake.
Patients included in the study will then be classified, on the basis of pre-pregnancy BMI, into 2 classes:
* normal weight (BMI 18-25)
* overweight (BMI 25-30) A specific diet will be developed for each patient, which will also take into account any food allergies or intolerances.
Each diet will be then eventually modified and revised throughout the pregnancy, according to the evolution of the same.
Patients will then continue their regular obstetrical examinations at the Obstetrical Day Hospital, every 4 weeks in case of uncomplicated dichorionic twin pregnancy and every 2 weeks in case of uncomplicated monochorionic twin pregnancy.
Once a month, in coincidence with the appointment at the Obstetric Day Hospital, the enrolled patients will be evaluated by the dedicated team of nutritionists.
