Update: we met with the cardiologist today. She has put through a referral for an urgent CT angiogram but is worried it might take 2 months, so if she can’t get it sooner, they’re going to do a regular angiogram. Also referred for a cardiac MRI and has a holter monitor on. Hoping these tests will
At first I was very biased because I thought maybe I am just overexaggerating a bit. However, the longer I started taking this magnesium supplement, the more I started to realise that this stuff is legit. It has gotten to a point where I don't even experience a severe headache anymore when having a
I had physiotherapy for two years, giving me massages, exercises and dry needling. It sure did improve my health situation, but I noticed that it only had a temporary effect. The therapist then finally suggested me to see a neurologist. Since then I got diagnosed with "out-of-the-sudden" chronic mig
NOTE: Progress updates posted below the main post. I am 59, my wife is 57. We met with Dr. Alan Green in NY on Thurs., and return home next Wednesday (we live in Honolulu) when we will fill our Rapamycin prescriptions (Sirolimus) and begin our program in earnest. Along with Rapamycin, we both curren
(female, 24). 173 cm, 56 kgs, smoker (nicotine). For the past seven years I have been getting what several doctors have diagnosed with “chronic migraines” on a daily basis although the severity changes. A migraine. Every single day. For 7 years. No treatment is working. So you can imagine my desper
BELGIUM (West-Vlaanderen) My wife’s suffering from migraine since 2018. No pain relief found, on the contrary, quantity and intensity raises by day. Since 1st January 2026 she had 3 pain free days in 50 days… average pain index 6-7/10 (not able to function, in bed or zombie). Last 2y she’s working
Is there any clinical reason to use two ARBs together ? (i.e. candesartan 8mg + valsartan 40mg). I can wrap my head around ACEi + ARB combo for extremely resistant and maybe it helps some minority of patients. But this makes no sense to me.
Don't downvote this to oblivion like other comments I've made on this subject in the past. I'm merely curious. I hear all the time that drug prices in the US are really exorbitant in comparison to other parts of the world. So I just wanted to gauge the price between where I am in Australia and the U

I’m a 32M and went almost my entire 20s not worrying about or even checking my blood pressure. When I was 30 I began having tachycardia episodes with high blood pressure readings which I had to go to ER for 3 times in a period of a few months with my readings at around 190/100 I got on losartan 100
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
Hello all. I’ve been diagnosed with hypertension since 2021. I take losartan 12.5 mg 2x day, hydralazine 100mg 3x day , Carvedilol/coreg 25mg 2x day, amlodipine/norvasc 10mg 1x day (mornings), aspirin 324mg 1x day and a vitamin b12 as directed by my doctor. Yesterday I stood up and went into the kit
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 wanted to share with this group since I’ve gained so much value from this forum. Sometimes I think people don’t share their positive results enough, and it can really skew people’s ideas of what medicating hypertension will be like. I put off getting medicated for 15 years. My story was basically
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
25M. When I was first diagnosed with hypertension (late 2022), I was hesitant to start any synthetic medication. I tried the “natural” route first — mainly beetroot juice. It did help a bit, but having to constantly buy, wash, cut, and juice beets was too time-consuming with my schedule as a univers
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

Candesartan is a ARB, while Losartan belongs to the ARB (Angiotensin II Receptor Blocker) class. This means they work through different pharmacological mechanisms, which may influence both efficacy and side effect profiles.
Both medications are approved for Hypertension. When two drugs treat the same condition, the choice between them often depends on the patient's medical history, other medications, tolerability, and prescriber preference.
Losartan carries 1 FDA warning. Patients should discuss all warnings and contraindications with their healthcare provider before starting or switching medications..
