Niacin- Mangel - Symptome
Niacinmangel ist charakterisiert durch die sogenannte 3- D - Symptomatik: Dermatitis (anormale Hautveränderung), Diarrhöe (mehr als 3 Entleerungen eines zu flüssigen Stuhls pro Tag) und Demenz (geistiger Verfall, "Verdummung"). Niacinmangel führt über Appetit - und Gewichtsverlust, Unwohlsein und Schlaflosigkeit sowie Schwindelanfällen letztendlich zur Pellagra (durch Vitamin B3 entstehendes Krankheitsbild; scharf begrenzte, ödematöse Dermatitis). Eine partielle Atrophie (Gewebeschwund) der Darmschleimhaut ist die Ursache der Diarrhöe und als Ursache der neuropsychiatrischen Veränderungen wird vorwiegend ein Mangel an Serotonin im Gehirn angesehen. In Entwicklungsländern sind Proteinmangel und einseitige Ernährung mit Mais oder Sorghumhirse die häufigsten Ursachen von Pellagra. Meist entstehen Pellagra - Symptome durch Alkoholismus oder bestimmte Krankheiten, wie der vererblichen Hartn up - Krankheit oder bei erhöhtem Verbrauch an Tryptophan zur Serotoninsynthese. Der Nicotinsäurestoffwechsel kann aber auch durch verschiedene Arzneimittel an unterschiedlichen Stellen gestört sein und dadurch einen Niacinmangel hervorrufen.
Niacin spielt besonders bei der Energieversorgung des Körpers eine bedeutende Rolle, da es sowohl am Eiweißstoffwechsel, als auch am Fett - und Kohlenhydratstoffwechsel beteiligt ist. Darüber hinaus ist Niacin wichtig für die Erholung unseres Körpers. Besondere Bedeutung hat es dabei für die Regeneration der Muskeln, der Nerven, der DNA und der Haut. Außerdem fördert Niacin im Gehirn die Bildung von Botenstoffen, mit deren Hilfe Informationen von Nervenzelle zu Nervenzelle transportiert werden. Schließlich ist Niacin auch für einen geregelten Ablauf der Verdauung von Bedeutung.
