The present invention relates to compounds which are capable of exerting an inhibitory effect on the Na+ glucose cotransporter SGLT in order to hinder glucose and galactose absorption, as well as on lipase thus reducing dietary triglyceride metabolism, for use in the treatment of conditions which benefit therefrom (diabetes, Metabolic Syndrome, obesity, prevention of weight gain or aiding weight loss). These compounds comprise a non-absorbable, non-digestible polymer having a glucopyranosyl or galactopyranosyl or equivalent moiety stably and covalently linked thereto, said glucopyranosyl or galactopyranosyl moiety being able to occupy the glucose-binding pocket of a SGLT transporter.
