Today went to see my cardiologist and no longer need to take losartan nor atorvastatin ! Got to a healthy weight and good diet that he said I no longer need the medication. Hopefully I can stay off it from now on. Im 5,8 went from 225lbs down to 185, eating a lot of food with high sodium to no/low
Hi, how is it going. Today I'm officially off blood pressure meds completely. With lifestyle changes, low sodium diet, low sugar, aerobic exercise and weight loss. I had blood pressure in the 170 to 180 systolic in January of 2025 after heart surgery on November 2024. I was 230 pounds and am current
I take 100 mg of Losartan daily, but before meds I was easily in the 140-150/90-100 range. Even after taking medication I was usually in the 130/90+ range. My resting heart rate used to sit at about 110 too. I felt like shit and my bod was so tense. But recently I stopped drinking and smoking and be
My blood pressure (seemingly) started giving me problems beginning of this year and I was put on losartan 50mg. I take that once a day and it seems to control my BP well (below 130/80). However, in the 4 months I've been on this medication, I've noticed when I'm on my period, my blood pressure shoot
Just felt compelled to write my positive experience with amlodipine. I've had high blood pressure for about 3-4 years. Average wasn't anything crazy, but around 150-160/90. I was prescribed 50 mg if Losartan, which seemed to do nothing. But I've been in it for the last 2 years. Finally, I decided Lo
I am a 35 year old male, recently diagnosed with stage 1 borderline stage 2 hypertension, my doc started me on 50 mg Losartan right away. I have a history of depression and anxiety and have tried Celexa, Lexapro, before finally settling in on Wellbutrin for a few years now, which has kept my normal
25m. I visited the doctor 2 months ago and was diagnosed with high bp and was put on 50mg Losartan. Was usually in the 150s/90 for the first week then it slowly worked but after my monthly visit back my doctor didn’t like the numbers so my dosage was doubled to 100mg. After 1 and a half months of lo

Male , 26. So I had a bit of a shock yesterday. Went to the doctor for a regular check, they took my BP three times within a few minutes: 153/100 165/103 145/95 The doctor immediately prescribed me 25 mg metoprolol. But here’s the confusing part — at home I’ve been checking for the past 1.5 years, a
I have been working on my hypertension since 2019 when at a company health check my BP was 170/110. I am on metoprolol and htcz. I white coat quite badly but I'm working on that. Today at the office reading came in 115/70. Felt good to find the right doses.
I’ve had hypertension since my early 20’s and was initially prescribed lisinopril and later perindopril (both ace inhibitors) to control it. My numbers were usually “ok” with those meds, but unfortunately I developed the ace inhibitor cough and asked my doctors about alternatives. He originally pu
My last few doctors appts I’ve had high blood pressure and I chalked it up to white coat hypertension. And then it happened again so I opted to start tracking at home. Unfortunately it was high at home. I am overweight (I need to lose about 70lbs), but I’m only 32. I also have HORRIBLE anxiety abou
Quick background: For the last several years, I (33m, 6'2", 235 lbs) had been on different combinations of lisinopril (with and without HCTZ), amlodipine, and metoprolol and my pressure was generally in the 140 - 150 / 100 - 110 range. Couple months ago, I went to a new doctor (old doc moved away) a

I’ve told my friends and my partner and they understand a little but I just wanted to share with some people who have had similar experiences. I’m 33 and have had blood pressure problems stemming from a shitty diet and alcoholism. Despite that, I somehow have managed to stay an ok weight at 200lbs,
Hi everyone! So this is more of a venting post. I’ve had high bp since I was about 22/23 when I was pregnant with my first son (I’m 36 now) so quite a while. It runs pretty deep on my dad’s side, so yea, here we are. Anyway, my bp has been pretty difficult to manage since my last pregnancy (2020) an
