If having blood work done for physical in morning can you drink water before? Doctor said no food or coffee

If having blood work done for physical in morning can you drink water before? Doctor said no food or coffee

Yes: Fasting labs are generally aimed at looking at blood lipid and glucose levels. These would generally be unaffected by moderate water intake prior to testing. Actually, being dehydrated when the sample is drawn may more likely cause abnormal values. A caution would be if you were to drink excessive amounts of water and diluted your blood. This would be unlikely in normal circumstances. ...Read more

Fasting blood sugar 181.8, hba1c > 7%, taking all vitamins, exercise 6 hrs/week, eat no sugar, eat high fibre, drink water, juice, wt. 67kilo, ht 5'5"?

Fasting blood sugar 181.8, hba1c > 7%, taking all vitamins, exercise 6 hrs/week, eat no sugar, eat high fibre, drink water, juice, wt. 67kilo, ht 5'5"?

Look into Paleo : Your lab numbers suggest you're on the path to diabetes. Even though you don't eat "sugar" any fiber or starch that your body can digest turns into sugar and fruit juice is sugar. Even things like diary that is thought of as healthy has sugar (lactose is a type of sugar). A person with lab numbers like yours has to limit all sugars and heal the damage. The paleo approach can help you do both. ...Read more

Can drinking "smart water" or water with electrolyes that is carbonated before a full blood lipid panel/blood work alter results?

Can drinking "smart water" or water with electrolyes that is carbonated  before a full blood lipid panel/blood work alter results?

No: There is no such thing as "smart water". It is just a scam to separate the not so smart people from their money. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex, if you have sex. ...Read more

I get horrible migraines whenever i donate blood or have it drawn. i always make sure to eat before and after and drink water. could this mean anythin?

Mind over body: If even a small lab draw can trigger you, then it is not something like volume depletion...it is your eyes, or pain response, or thought process that is likely triggering a physiologic response (aka: stress or "fight/flight") and those hormones are contributing to triggering your migraine. Should talk to your Dr and consider positive imagery / biofeedback / similar PREEMPTIVELY to minimize/stop. ...Read more

I drink water regularly and sometimes soda but I went to pee and it had blood in my pee?

Time for a trip...: When there is blood in the pee, regardless of what one is drinking, it's time to take a trip to one's primary care doctor. Blood can be real blood, as in bladder infections, bladder tumors, reactions after strep infections, etc... Occasionally, urine can look bloody (but is not real blood, but is color from muscle breakdown products) after a strenuous athletic event. ...Read more
