Erythropoietin (EPO) & its synthetic buddy rEPO
- What is rEPO?
- Think of it as a magic potion that athletes hope will produce more red blood cells. ๐ฉธ
- Why is rEPO unpredictable?
- ๐ฒ It’s a gamble! We can't predict the number of new red blood cells produced.
- The Downside of Playing with rEPO
- **Thick Blood Alert!**๐จ
- With too many new red blood cells, our blood can get super thick (like that super thick milkshake that's impossible to sip!). This is called increased blood viscosity.
- Blood Clotting Drama
- Thick blood = higher risk of clots!
- Clots can lead to ๐
- Heart attacks
- Strokes
- Heart failure
- Why the drama with blood clots?
- EPO parties with platelets and the inner blood vessel lining, making clotting more likely.
- Athlete Trick ๐ดโ๏ธ๐: Some combine rEPO with iron injections.
- Goal? Boost oxygen-carrying blood capacity!
- Issue? Too much iron = big problems, especially for our liver!
- High Blood Pressure: After using rEPO, blood pressure goes ๐ during moderate exercise.
- Mystery Alert! ๐ต๏ธโ๏ธ We're not 100% sure why.
- Real-world Link: Cyclists and rEPO - A sad fact: Over 20 cyclists are believed to have died due to rEPO use. ๐ดโ๏ธโ
- **Thick Blood Alert!**๐จ
Beta blockers the good the bad & the ugly
-
Why do people use them?
- They can slow down heart rate and reduce stress. Sometimes used to calm nerves in non-endurance sports. ๐๏ธโ๏ธ
-
Health Concerns
- Asthma + Beta Blockers = No Go
- Can cause bronchospasms! (Imagine trying to breathe through a straw. Not fun! ๐ฅค)
- Heart Troubles
- People with heart problems? They might face cardiac failure!
- Diabetes & Beta Blockers
- Ups insulin secretion = risk of low blood sugar (hypoglycemia) for type II diabetics.
- Asthma + Beta Blockers = No Go
-
Common Side Effects
- Brachycardia: Heart's going slow-mo (super low heart rate! ๐ขโค๏ธ).
- Orthostatic Hypotension: Stand up and... whoa! Big drop in blood pressure.
- Dizziness: You know, like after spinning in circles!
- Heart Arrhythmias: Erratic heartbeats! Imagine a drummer who can't keep time. ๐ฅโค๏ธ
- Feeling Super Tired: Makes sense, right? A slow heart might make us feel sluggish. Not what an athlete wants!
