Kidney Disease
In addition to itchy skin, anemia, or edema, people with chronic kidney diseases can also suffer from hiccups. However, this tends to be a much lesser complication and often goes undiagnosed. In most cases, the condition just lasts for a couple of minutes, but extended episodes might be symptoms of a possible stroke, meningitis, or multiple sclerosis. Basically, it is caused by an electrolyte imbalance, effects of anesthesia, or some drugs. If hiccups keep occurring for more than 2 days, it is better to consult your doctor to get a proper diagnosis and better treatments. [10]
