Anticipating the Baby
Expectant mothers and their doctors can take the secure thought that hundreds of women with periodic paralysis have been members of our Listserv since 1995, and an overwhelming majority of them have been mothers. To date not a single one has been unable to care for her child due to her periodic paralysis.

Do you suspect that you might have periodic paralysis? The periodic paralyses are a rare group of disorders and there are many conditions which cause an imbalance in serum potassium. So how does the doctor tell the difference between paralysis or weakness caused by an ion channelopathy and any of the other numerous disorders, conditions and reactions which might produce the same symptoms?

In 2009 Professor Dr. Frank Lehmann-Horn of Ulm University, Ulm Germany, gave a presentation on managing hypokalemic periodic paralysis at the Periodic Paralysis Association's conference held in Orlando Florida. This presentation contained so much valuable information in such a compact and understandable format that we asked Dr. Lehmann-Horn for his permission to include it on our website, for the benefit of physicians and patients.

The normal renal response when hypokalemia is due to non-renal causes is a TTKG <2, where a TTKG >5 is indicative of increased secretion of K+ in the cortical collecting ducts. Thus a transtubular potassium concentration gradient (TTKG) of greater than 3.0 indicates hypokalemia of renal origin, while a value below 2.0 indicates intracellular shift of K+, as found in ion channelopathy hypokalemic periodic paralysis.
