how long would it take to become severly dehydrated especially if you had an underlying infection?

Question

what if you also had dementia that left you confused and aggresive so these symptoms may confuse your diagnosis

Answer 1

Dehydration symptoms generally become noticeable after 2% of one's normal water volume has been lost. Initially, one experiences thirst and discomfort, possibly along with loss of appetite and dry skin. Athletes may suffer a loss of performance of up to 50%, and experience flushing, low endurance, rapid heart rates, elevated body temperatures, and rapid onset of fatigue.

Symptoms of mild dehydration include thirst, decreased urine volume, urine that is darker than usual, unexplained tiredness, lack of tears when crying, headache, dry mouth, and dizziness when standing due to orthostatic hypotension.

In moderate to severe dehydration, there may be no urine output at all. Other symptoms in these states include lethargy or extreme sleepiness, seizures, sunken fontanel (soft spot) in infants, fainting, and sunken eyes.

The symptoms become increasingly severe with greater water loss. One's heart and respiration rates begin to increase to compensate for decreased plasma volume and blood pressure, while body temperature may rise because of decreased sweating. Around 5% to 6% water loss, one may become groggy or sleepy, experience headaches or nausea, and may feel tingling in one's limbs (paresthesia). With 10% to 15% fluid loss, muscles may become spastic, skin may shrivel and wrinkle, vision may dim, urination will be greatly reduced and may become painful, and delirium may begin. Losses greater than 15% are usually fatal.

Answer 2

The following statements are not medical advice. I have never heard of any person with dementia getting severly dehydrated quicker than anyone else. I would believe that the severe dehydration would be based on these 3 things:

1. How much water a person takes in.
2. How hot or humid the temperature is outside.
3. How long a person is outside in the heat.

Answer 3

To become severely dehydrated would depend upon many different factors. If the person was vomiting or had diarrhea they could become dehydrated very fast.

Dementia can be caused due to dehydration. Therefore the dementia can be a result and not necessarily a symptom of what is wrong.

If you were healthy and in a cool climate but didn't take in any liquids you could become dehydrated in about 10 days. If you were in a hot climate or had diarrhea you could become severely dehydrated in 2 days.

Answer 4

If you have a fever or heavy sweating due to the infection. 24 hours tops.

Dehydration can not be confused. Simple test: Pick up the skin on the back of the hand. It should stretch back immediately. If not you are dehydrated.

Answer 5

3 days no water or liquids = muerte.
There is a liquid intake rule of thumb. I forget what it is. However, if you are able to pinch the flesh between the primary index finger and it doesn't retract right away, hydrate. Yes, lack of fluids can exasperate any condition

Answer 6

I would say about 3-4 days

Answer 7

I think If the climate is dry and hot summer then it can happen in just one day itself.

Answer 8

I would guess one and a half to two weeks with no water. Going on your third week will kill you. Literally

Answer 9

Get to a doctor, quick.

Answer 10

really depends on your physical condition to start with.
