Arey, trying to lose weight to look good but then facing this issue is a cruel joke! Yes, phentermine affects your nervous system and blood flow, which can definitely cause ED. Sometimes we try to fix one thing and another part just goes on strike.

Bro, yes, stimulant-based diet pills like phentermine constrict blood vessels, which is a total mood killer for your erections. It usually goes back to normal once you stop, but definitely don't ignore it. Talk to your doc.

Yes, it can. Since I manage diabetes, I know how sensitive blood flow is, and weight loss drugs like phentermine can mess with your system. Please don't take these pills without a doctor's strict prescription, and mention this side effect to them.

To be honest, yes, it happened to me when I was on it. It reduces your libido and makes things difficult down there because of how it stimulates your body. I had to talk to my doctor and switch to another plan because it wasn't worth it.

Please don't ignore this side effect thinking it will just pass. I once ignored some warning signs while taking heavy supplements and ended up with long-term issues. Go back to your doctor immediately and tell them what you are experiencing.

Yes, it definitely can cause ED due to its effect on the nervous system. You should consult your doctor about reducing the dosage or stopping the medication.

Yes, since phentermine is a stimulant, it acts like an amphetamine and narrows blood vessels, which can lead to temporary erectile dysfunction. It's a known side effect. Please discuss this with the prescribing doctor so they can adjust your dose or suggest an alternative.
