Jakuji Katsura Dies at 64, Doctors Warn of Untreated Diabetes

Heart attack and stroke caused by diabetes.

The sudden death of rakugo performer Jakuji Katsura at the age of 64 shocked many people. He collapsed while playing golf and was rushed to the hospital, but unfortunately passed away. According to those close to him, diabetes was a contributing factor to his sudden death, but because he had been living normally up until the incident, the surprise among those around him was immeasurable.

However, Dr. Yoshimasa Goto of Gorakai Clinic in Shirokane-Takanawa warns, “Sudden death due to diabetes, like with Katsura, is not uncommon.”

“In Japan, it’s estimated that there are about 10 million people with diabetes or at risk of diabetes. One in four people over the age of 50 are affected. This is a significant number that cannot be ignored.

When blood sugar control is not properly managed, it leads to damage to blood vessels throughout the body. Atherosclerosis progresses, and the risk of coronary artery disease and cerebrovascular disorders increases by two to four times. Heart attacks and strokes can be life-threatening, and the aftereffects are severe, so early intervention is crucial.”

As people age, the secretion of insulin decreases, and the body’s response to insulin weakens, making the risk of diabetes for middle-aged and older adults three times higher than for younger individuals. What’s frightening is that diabetes is often called a silent killer because it often progresses without noticeable symptoms.

“When blood sugar is only slightly high, you usually don’t feel any abnormality in your body. As a result, diagnosis is often delayed, and by the time it’s noticed, the blood vessels may already be significantly damaged,” said Dr. Gotoh.

 End-stage kidney failure, cirrhosis of the liver, and liver cancer.

Middle-aged and older individuals should be cautious about symptoms that are often dismissed as just age-related.

“Frequent trips to the bathroom at night, feeling unusually fatigued, and inability to concentrate in the morning—these mild symptoms are often caused by diabetic neuropathy or the effects of high blood sugar, but many patients don’t realize it,” says Dr. Goto.

If these symptoms are ignored, they can lead to serious complications such as diabetic nephropathy or retinopathy. “Diabetic nephropathy is a major cause of end-stage kidney failure, which requires dialysis. Delayed diagnosis increases the risk of vision impairment or blindness,” Dr. Goto warns.

Diabetes is also closely related to metabolic-associated fatty liver disease (MAFLD). If left untreated, it can progress to cirrhosis of the liver and liver cancer, so early detection and treatment are critical.

It was liver failure caused by diabetes that ultimately claimed the life of Mr. Katsura.

“Especially after the age of 45, it’s important to get an annual health checkup. Fasting blood sugar levels, HbA1c, liver function, and kidney function should always be checked. These tests are the first step in preventing not only diabetes but also damage to related organs,” he adds.

When improving lifestyle habits, it’s important not to overdo it.

“If you try to change your life all at once, you won’t be able to sustain it. Start with a 15-minute walk every day. Also, it’s essential to avoid consuming too many carbohydrates and focus on a balanced diet centered around vegetables. You should also be mindful of hidden sugars in processed foods and drinks.”

Dr. Goto strongly emphasizes at the end:

“You might think ‘it’s still okay,’ but by the time you realize it, it might be too late. If Mr. Katsura Jakuji had addressed it earlier, his life could have been saved. If abnormalities appear in your health check-up, don’t hesitate to see a doctor.”

In your 50s and 60s, you play important roles both at work and in your family. Paying attention to your health and facing your body properly will be the key to making the most of the years ahead.
