<s>[INST] My blood pressure has always been stable at 120/75 even during pregnancy and the most stressful times.  I have recently been to get a repeat prescription of my HRT - Femiston 2/10mg and my pressure check showed as 152/100.  This is obviously high, what could have caused it.  I have to go back for another check in 3 weeks. [/INST] Hello and thank you for using Chat Doctor. I carefully read your question and I understand your concern. I will try to explain you something and give you my opinion. You should know that we talk about hypertension if we have mean value that exceeds 140 / 90 mmHg. A person might have high value during emotional and physicals trees so It's mandatory to judge on mean values. Hypertension is divided into two groups. Essential hypertension that is a chronic disease and should be treated all live long. It has not an identified cause and is frequent in older agesSecondary hypertension, meaning that it's a secondary house of it. This is found in younger ages and the cause might be renal, endocrine or any cardiovascular anomaly. Resolving the causing factor might resolve hypertension. As you explain, you are under hormone replacement therapy. This makes me thing that you might be near or in menopause. It is quite known in cardiology that hypertension does appear in women during this period. So, if I was your treating doctor I will recommend some examination like a cardiac echo, a full blood analyze and a holder pressure monitoring to evaluate your values during day and niftier this we can better judge how to treat the problem. Hope I was helpful. Best regards, Chat Doctor.  </s>
