Hello and thank you for using HCM.I carefully read your question and I understand your concern . I will try to explain you something and give you my opinion. In young patient like you, before starting to treat hypertension its important to exclude secondary hypertension. There are different factors that might be responsible for secondary hypertension like endocrine problems, renal disease, cardiovascular anomalyes ect. So,if I was your treating doctor I will recommend some examination like a cardiac echo, a full blood analyze, your urinary chatecolamins, an abdominal echo to evaluate renal structure and a holter pressure monitoring to evaluate mean values. Only after excluding secondary factors than we can judge how to treat it depending on mean values. Diovan is a good treatment, but the dosage depends on your mean values not in a sporadic value.Normaly we start whith lower dosage, 80 mgand than increase it., depending on mean values. Hope I was helpfull. Best regards , Dr.Ervina.
