Obesity is a term that means you weigh at least 20% more than what is considered a normal weight for your height. It makes you more likely to have conditions including: Heart disease and stroke.
An Isotonic Solution creates a mild, less concentrated salt solution of 9mg of Sodium Chloride per mL of water, which has a similar salt concentration as your body and may be more comfortable to use for some people initially compated to the more concentrated Hypertonic solution.
Hypotonic fluids have a lower salt concentration, whereas hypertonic fluids have a higher salt concentration. When giving sub-Q fluids, you usually use isotonic fluids. There are a variety of fluid types available, but the fluid that is most commonly used for CKD cats is Lactated Ringers Solution (LRS).luids containing dextrose also have a shorter life than non-dextrose fluids. If your vet gives you this fluid (it may be a bag of LRS to which 2.5% or 5% dextrose has been added, so always check bags carefully before using them), ask to exchange it for a more suitable type.
