I think I might have made a mistake with my labs but I learned something from it.
Yesterday I went in for extensive lab work. Fitomics had a sale late last year so I bought several panels checking liver, kidney, heart, blood, lipids, Hgb A1c, etc. My job also pays me to check lipids and biometrics annually so I took their form also. Lipid results returned this morning.
The results are interesting. Fasting glucose is within range. Triglycerides and LDL are great. HDL increased from 33 to 37 which is still low but better. But total cholesterol dropped from 133 to 95. Apparently your total cholesterol can be too low but the experts are unsure what the consequences could be from LDL or total cholesterol being too low.
For reference I take 10mg Crestor and 10mg Zetia daily. I added Zetia 3-4 weeks ago to see if my HDL would increase.
Where I might have made a mistake is Sunday I completed a 7 day cycle of doxycycline, then had labs on Wednesday.
I looked up the impacts of antibiotics on lab work and this is what I learned.
1. Impacts to white blood cell count which was to be expected but I don’t have those results back yet.
2. Some antibiotics can reduce RBC.
3. Because many antibiotics are metabolized in the liver the liver function test, ALT and AST could be elevated.
4. Some antibiotics are hard on the kidney causing BUN and creatinine to be elevated.
5. I found a study that found that Doxycycline reduced liver cholesterol, increasing HDL but lowering total cholesterol. Also, “Glucose and insulin tolerances were improved, accompanying with reduced fasting blood glucose, insulin, HOMA-IR and advanced glycation end products.”
I might redo some of these labs in a few weeks. Most guidance I found was you should wait a few days after completing your antibiotics before getting lab work but didn’t state exactly how many days.
Here is an article discussing the impacts of doxycycline on cholesterol levels.
The aim of this study was to determine whether low dose doxycycline as an anti-inflammatory agent could improve glucose metabolism in diabetic animals. Therefore, doxycycline was supplemented in drinking water to 6-week-old male db/db mice for 10 weeks. Doxycycline reduced perirenal/epididymal...
