Elevated thirst and urination (polyuria polydipsia – PUPD) are additionally frequent signs.
What Is Low Hypokalemia In Cats?
The conventional blood potassium of a cat must be 3.5 and 5.5 mEq/L (3.5 – 5.5mmol/L). Hypokalemia implies that the blood potassium is decrease than these ranges. Hyperkalemia, or excessive blood potassium, would imply that the blood potassium is increased than these ranges.

The place In The Physique Is Potassium Saved?
A lot of the potassium within the physique stays inside all dwelling cells. Nonetheless, there’s a continuous regular however decrease quantity of potassium within the bloodstream and within the fluid across the cells. The partitions of cells have an energetic pumping mechanism that ensures that the proper degree of potassium is maintained inside and out of doors cells.
The gradient of potassium focus between the 2 “compartments” (intracellular and extracellular) is vital to regular functioning of some cells. That is significantly vital for muscle cells. If potassium ranges go unsuitable, the operate of the muscle cells is badly affected.

How Are Blood Potassium Ranges Maintained At The Right Degree?
Hormones within the physique, primarily aldosterone produced by the adrenal glands, make sure that the blood potassium stays inside regular limits. Potassium is excreted from the physique within the urine, and aldosterone governs the speed at which this occurs.
Regular potassium ranges are critically vital for the traditional operate of a variety of various features of the physique, Particularly, it’s important for regular muscle operate (together with the guts muscle). Issues of potassium ranges in cats are frequent, however as a result of the indicators are typically imprecise and common, they could solely be recognized when blood samples are taken to measure potassium ranges.
Signs Of Hypokalemia In Cats
Muscle weak spot, technically brought on by “polymyopathy” (which means “illness of many muscular tissues”) is probably the most noticeable medical signal seen in hypokalemic cats.

In delicate instances the place the potassium ranges are simply marginally low, there could also be no outwardly discernible indicators that one thing is amiss, however there may be nonetheless a danger that the low blood potassium has a big impact, inflicting a lowered urge for food and affecting kidney operate. That is why it’s value monitoring blood potassium ranges in cats which may be susceptible to lowered ranges.
Causes Of Hypokalemia In Cats
The commonest causes of hypokalemia in cats are:
- Persistent kidney illness (CKD) – Often known as Persistent Renal Failure (CRF), or simply kidney failure, it’s the commonest reason for hypokalaemia in cats. Affected cats lose massive quantities of potassium of their urine, for causes that aren’t totally understood. As a consequence, the blood potassium ranges fall.
- Gastrointestinal upsets – Vomiting and diarrhea, brought on by quite a lot of totally different causes, trigger low potassium ranges due to the direct lack of potassium from the physique within the waste.
- Main aldosteronism – On this uncommon situation, a tumor on the adrenal gland produces abnormally excessive ranges of the hormone aldosterone, leading to extreme excretion of potassium within the urine.
- Hereditary hypokalemia – That is generally seen in Burmese cats, in addition to in different associated breeds of cats (see record under). The mechanism by which this occurs remains to be unknown however there may be now a greater understanding of the genes concerned. It’s attainable to display screen potential breeding cats to make sure that they don’t seem to be carriers.
- Different ailments – Much less generally, low blood potassium is seen when cats produce other ailments (resembling hyperthyroidism) or as a aspect impact of treatment (e.g. diuretics or different medication being given for coronary heart illness)
