Presbyopia suddenly disappears, white hair suddenly turns black...6 diseases that suddenly "get better" are more dangerous!

In life, if a disease that has troubled you for a long time suddenly gets better, many people will definitely be very happy.

But if you have any of the following conditions and they suddenly "get better", it may not necessarily be a good thing. On the contrary, it may be more dangerous. Be careful!

01

Presbyopia suddenly improved

It could be diabetes or cataracts

According to a report by Ningbo Evening News on November 15, 63-year-old Ms. Hu (pseudonym), who lives in Ningbo, Zhejiang, suffers from presbyopia and cannot see close objects clearly.

However, half a month ago, Ms. Hu suddenly felt that her eyesight had improved overnight . Even without wearing glasses, she could see the small print on her mobile phone clearly.

This change made her very happy for several days. However, she felt something was wrong: "How could my eyesight suddenly get better?"

So she went to the hospital's ophthalmology department for a checkup. The results were shocking: Ms. Hu's fasting blood sugar was as high as 20 mmol/L, while the normal fasting blood sugar level is 3.9 to 6.1 mmol/L.

The doctor suspected that the eye problem was caused by a sudden increase in blood sugar due to diabetes.

Why does presbyopia suddenly improve when blood sugar rises?

Hu Jingwei, deputy director of the ophthalmology department of the Second Hospital of Beilun District, Ningbo, Zhejiang, said that Ms. Hu's vision improvement was temporary. This was mainly because the increase in blood sugar led to a decrease in the content of inorganic salts in the blood, which allowed more water to penetrate into the lens, resulting in a convex lens phenomenon, which offset part of the presbyopia and caused a temporary improvement in vision.

When the body's blood sugar level drops, the patient's vision will return to its previous state, but the symptoms of diabetes will worsen. This is actually a typical diabetic eye disease.

Although Ms. Hu had known that she had diabetes before, she had never taken regular treatment and had not regularly monitored her blood sugar, thinking that as long as she had nothing serious wrong with her body, everything would be fine.

In addition, some people who originally had "presbyopia" suddenly can see clearly without wearing reading glasses after they reach the age of 60. At this time, you need to be more vigilant, because this is likely to be caused by cataracts.

There is a type of cataract, medically known as nuclear age-related cataract , which is mainly characterized by increased density, yellowing, and hardening of the lens nucleus, causing the refractive state of the eyeball to temporarily become myopic.

But as cataracts gradually develop, your eyes will have trouble seeing both near and far.

02

High blood pressure for many years suddenly became normal

Possibly heart problems

Ms. Zhang (pseudonym), who has suffered from hypertension for 11 years, has always had poor blood pressure control. However, her blood pressure suddenly became normal in recent days. She thought she was cured and was extremely happy.

But soon I felt chest tightness and went to the hospital for a check-up, which confirmed a heart attack.

The doctor explained that this is "normal blood pressure" caused by the disease, not that hypertension has been cured. It is because hypertension has caused obvious heart damage, so that the heart does not have the "strength" to pump more blood, and the decrease in cardiac output causes low blood pressure.

This can cause insufficient blood perfusion to important organs such as the brain, kidneys, and the heart itself, a condition that is more dangerous than high blood pressure.

03

Atrial fibrillation palpitations feel better

Maybe I just tolerated it.

Wang Xinhua, director of the Arrhythmia Diagnosis and Treatment Center of the Department of Cardiology at Renji Hospital affiliated to Shanghai Jiao Tong University School of Medicine, said that generally speaking, patients with early atrial fibrillation will feel more palpitations and their heartbeats will be sometimes fast and sometimes slow.

When it progresses to persistent atrial fibrillation, the human body may become tolerant to the above symptoms. Persistent atrial fibrillation may also cause a relatively slow heart rate, so the patient feels that he or she has "improved" and thus neglects treatment.

In fact, this is precisely the group of people who are most at risk and most in need of formal treatment.

04

Menstruation after menopause

Beware of the disease

Many women in their fifties are pleasantly surprised to have their periods again after menopause, as if they have encountered the "second spring" of their lives. But in fact, this may not be a good thing, as it indicates the onset of some diseases.

Song Fang, deputy chief physician of the Department of Gynecological Oncology at Beijing Obstetrics and Gynecology Hospital, reminds us that the common causes of postmenopausal bleeding are as follows:

1. Malignant tumors of reproductive organs

The most common is endometrial cancer, which accounts for about 80% of malignant lesions and is more common in elderly women. A considerable number of patients have diabetes, hypertension or obesity.

It is often manifested as continuous or intermittent irregular vaginal bleeding, and late bleeding may be mixed with rotten meat-like tissue. Others include cervical cancer, ovarian cancer, fallopian tube cancer, vulvar and vaginal tumors, etc.

2. Benign lesions of reproductive organs

Such as uterine fibroids, endometrial polyps, cervical polyps, etc., as well as some inflammatory lesions such as endometritis, senile vaginitis, etc.

If there is a history of persistent or intermittent irregular vaginal bleeding after menopause, and if ultrasound shows that the fibroids are growing rapidly and have rich blood supply, the possibility of uterine sarcoma should be highly suspected.

3. Taking medicine or health products

Some elderly women experience bleeding after taking estrogen, progesterone drugs, or health products containing these hormones.

The old man's white hair suddenly turned black

Or endocrine problems

When elderly people suddenly have gray hair turning black, many of their children think it is a sign of good health. However, if it is only a small number of cases, it may be due to recent changes in water and air quality, quality of life, etc., which may have caused changes in various metabolic levels of the human body.

If your hair suddenly turns white or black, it is often a sign of illness.

If some elderly people's hair suddenly turns black or white, especially if their skin is particularly delicate and their body functions are particularly good, it is often due to a lesion in a certain part of the body that causes an abnormality in the pituitary gland, and you should be particularly vigilant.

In addition, some chronic diseases of the endocrine and nervous systems can also cause endocrine disorders and lead to sudden changes in hair color.

06

The old man suddenly grew "new teeth"

Beware of tumors

People always say that "we lose teeth as we age", but some people grow new teeth in their 80s. A 90-year-old man in Chengdu has six "new teeth".

However, Yang Zheng, chief physician at the West China Hospital of Stomatology, Sichuan University, said in an interview that the elderly should go to the hospital for a check-up. In theory, a person grows teeth twice in his life, the first one is called deciduous teeth, and the second one is called permanent teeth.

People usually only have these two sets of teeth, and it is difficult to grow a third set of teeth. If "new teeth" grow, there are generally three possible reasons.

One possibility is that the permanent tooth crown is damaged or the root is broken and left in the alveolar socket. When the gums of the elderly shrink, the root is exposed again, making people mistakenly think that a "new tooth" has grown.

The second possibility is impacted wisdom teeth, which are buried in the shallow layer of the alveolar bone. In old age, the alveolar bone shrinks, making the impacted wisdom teeth exposed, as if a "new tooth" has grown.

The third possibility is a tumor.
