Have low blood pressure due to dehydration: How to hydrate?

You should be under a doctor's care for this:

@lenmayo so it's bad? How bad? (bad as in serious) The link you gave had instructions on what to do for mild to moderate dehydration.

@lenmayo, I have some guesses as to what you mean, but it's toa wide category as to what you mean. Can you explain further?

I'm 16yrs and about 5'3. I do a lot of biking and sweat a lot because of it. I've been dehydrated for years and now am having what seems to be low blood pressure because of it. I was wondering if anyone has ideas for getting re-hydrated. I can't seem to drink enough water. I've done electrolytes, and it helps enough to make a noticeable difference, but it just doesn't last long. I don't like drinking electrolytes every day, or even once a week. I don't know what to do, or if this is actually a problem. I've posted this somewhere else and someone said, "You should be under a doctor's care for this" but hasn't said what they mean. If you have any questions, please ask. I'll let you know if I don't want to answer.

Hi @khelves, it is nice to see you join Mayo Clinic Connect.

You may want to read through Mayo Clinic’s overview of low blood pressure if you haven’t already. https://connect.mayoclinic.org/member/00-d960125851a3c2ca531118/activity/discussions/

It may help to keep a log of blood pressure readings and maybe water intake along with symptoms. What symptoms are you having, and do you notice any patterns or trend? Do you plan to discuss your dehydration and low blood pressure with a doctor?

Hi @jlharsh. The link you included only leads to my pfp (profile page) not to any overviews.
In hopes of answering your question, I'll probably end up saying more then really necessary. In Oct, my PE teacher gave all the kids the assignment of reading blood pressure based on heart rate. Resting, directly after exercise, and recovery. As a really active kid, I didn't think anything of it until I didn't hit the range for directly after exercise. I was too low by at least 10. Everything else was within the rage she said teens should hit. Lately, I've had a hard time focusing on things that are normally easy, feeling lightheaded or slightly dizzy. Earlier there was a slight headache as well. I haven't paid the most attention to it, but I have had this happen before for short amounts of time that seemed to be solved on its own. Most often after sitting down for an amount of time. Things fall asleep much easier than they used to as well, but I figured it was because I have more school now, so I wouldn't be moving as much.

I don't really go to the doctor's office unless it seems to be serious, or possibly deadly. Examples include I didn't go when I over worked my wrist or cut my foot on a nail head. I have gone when I sprained my wrist, lost my sense of smell, and had chest pain from timed running for school. I have mentioned that I thought I had low blood pressure to mom, but it didn't really matter because I am often-ish do things that make me sore or such things and it usually isn't a problem. So, no, I'm not planning to as of right now. How often would you recommend checking blood pressure and writing it down?

Oh, geez! I will reply separately but quickly, here is the correct link for the Mayo Clinic Low Blood Pressure overview:

I am a much older person, but I have low blood pressure and I know for a fact, the majority of the problem is I don’t drink enough water. But you could try eating watermelon, Jell-O, And soups to get more liquid liquids in your body Along with drinking more water..
I am going to try and follow my advice to you for myself also. 😉
But it’s also a good idea to keep a log of your blood pressure. Hopefully you have a blood pressure machine at home.

@khelves Welcome to Mayo Connect - when the poster said "You should be under a doctor's care for this" they meant that the inability to stay hydrated, in spite of drinking enough water, can mean there is an underlying physical cause for your low blood pressure. We are not doctors, but even a doctor would not try to give you a diagnosis without examining you. A physical with some lab tests can lead to the answer.

At 16, have you made your adults aware of the problem? Have you seen a provider for a full exam - I don't mean Urgent Care or the Emergency Room - they are just there to handle the immediate issue, and would just tell you to go see your doctor. If you do not have medical insurance, find a Teen Clinic in your area that can help you.

@khelves Second response to you - you said, "As a really active kid, I didn't think anything of it until I didn't hit the range for directly after exercise. I was too low by at least 10... "
Your PE teacher should have gone on to explain that blood pressure is a VERY individual measurement. Until my first pregnancy at age 30, my usual, resting blood pressure was 90/60 - very low by most measures. Yet I functioned very well. Now, many years later, I struggle to keep my blood pressure down in the normal range, even with a very small dose of medication.
Chronic dehydration is a different thing - how are you determining that? In addition to tracking your BP and liquid intake (non-caffeinated) you might want to track how frequently you urinate. Do it every day or so for a month, then ask your Mom to send you for a physical.
