Since February 2020, many people around the world have reported suffering from intermittent symptoms, such as slight fever, malaise, strong fatigue, numbness, respiratory distress, headache, and loss of appetite, that have been appearing for a long time. Many people have also complained of poor physical condition after receiving the COVID-19 vaccination. As many as 30-40% of COVID-19 cases suffer from sequelae, even if the symptoms in the acute phase subside. The sequelae include dullness, difficulty breathing, abnormal tastes and smells, and a certain decrease of mental capabilities. Some patients have been able to return to their job places, but get tired much more easily as before and cannot cope with their daily activities. The treatment of these sequelae must take an integral approach that consider not only the physical aspects, but the mental dimension of the problem, too, and also offer support on their return to their working life. At our clinic, all our departments cooperate in our treatment of COVID-19 sequelae to provide only the best. The treatment consists mainly in NMN, but Western medicine and Chinese medicine are used as appropriate. We are currently receiving patients from places as distant as Hokkaido to Okinawa.

Fatigue, palpitations, and dyspnea after movement

You feel fine when you're at rest, but if you move a little hard, you'll get a slight fever or you'll be exhausted and unable to move. On situations like these, we can check the following two things. One is whether the oxygen concentration in the blood decreases or not when walking. If you had severe pneumonia at the beginning of the infection, you may still have scars on your lungs. As a result, your lungs do not expand properly when breathing, and you feel pain when moving. Number two is checking if there are any abnormalities in the autonomic nerves. At our hospital, we are paying attention to the somatic tachycardia syndrome that develops after COVID-19 infection. There are no symptoms when sleeping, but when you stand up or move, it hurts and you often feel awkward. In some cases, the causes are not clear. In that case, we continue to provide medical care, paying attention to other possibilities, such as decrease in muscle strength or mental stress.

Hair loss

Many people complain of hair loss a short time after the onset of infection (about 1-2 months). Women with long hair are especially likely to complain that the drains in their bathrooms are easily clogged with hair, or that hair flies out when they dry their hair with a hair dryer. Hair growth has a cycle of growth phase, regression phase, and resting phase. Hair loss after infection with the new coronavirus is called telogenetic alopecia, in which the cycle becomes dormant due to the infection. People are concerned that they will lose all of their hair, but it does not mean that all of their hair will fall out, only that the hair will fall out more easily overall. We recommend the use of over-the-counter hair growth products and treatment for circular hair loss, which settles down about 6 months after the onset of the disease. If symptoms are severe, we collaborate with university hospitals for treatment.

Inability to think clearly, poor judgment, memory loss

From the early stages of infection, memory loss may appear, such as inability to understand what people say or write (trying to understand is very tiring), making mistakes that would not normally be made, and inability to remember or recall. The overall feeling of a foggy head is also known as brain fog. We provide ongoing treatment using NMN therapy.


Headache is a symptom of brain fog, which can be a worsening of an existing headache or the appearance of a new one. Although Kalonar and Loxonin, which are commonly used as analgesics, are often ineffective, NMN treatment may improve symptoms. We also use Chinese herbal medicines and antidepressants in combination with headache treatment.

Anxiety, insomnia, feeling depressed

Many patients complain of anxiety and insomnia when we interview them. Although anxiety is often caused by other post-traumatic symptoms, some patients are diagnosed with depression because their main symptom is a low mood.
Some patients are diagnosed with depression because their main symptom is low mood. In some cases, the main symptom is depression. In other cases, a history of depression or manic-depressive episodes may flare up again after a new type of coronavirus infection. We provide mental care by nurses and treatment in cooperation with the Department of Psychosomatic Medicine.

Numbness and pain in the body

Many patients complain of vague body pain or localized numbness, such as a tingling in the chest, numbness in the limbs, or an overall strange sensation in the body. We search for other causes. After infection, joints in the limbs become swollen like rheumatism, and some patients have difficulty in their daily lives. General painkillers such as Loxonin are not effective, so we sometimes use the same treatment as used for rheumatoid arthritis. In our clinic, we treat patients with NMN therapy.

Chronic fatigue syndrome

Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is a disease that causes extreme fatigue and other symptoms after slight exertion.
Many people who exercise for the sake of "physical fitness (muscle strength)" rapidly deteriorate afterwards, so if you are feeling tired, please be careful to move only as much as you can inside your home without becoming tired.
In our clinic, we measure NAD and treat patients based on the results.


Other symptoms include heartburn, diarrhea, tremors in the hands during exercise, sudden sweating, and redness of the feet. Symptoms of heartburn improved with treatment for reflux esophagitis and diarrhea improved with treatment for sensitive bowel syndrome. Symptoms that are thought to be sequelae of the new coronavirus infection may worsen if other diseases are hidden or if there is an underlying disease.
