Introduction: Before a serious illness comes, the body often calls the police. However, some symptoms that appear at night are easily overlooked. So what are the symptoms of physical discomfort that suggest illness? Give you some symptoms that are easily overlooked.

Dyspnea-asthma or heart disease

Asthma can wake a sleeping patient at night. Dr Charles Knight, a cardiovascular disease expert at Bartz Health Clinic in London, said that when a patient lies down, mucus is more likely to accumulate in the respiratory tract, which increases lung pressure and leads to poor breathing. If you wake up after falling asleep for two hours, it may be a signal of heart disease or even heart failure. Suggestion: In this case, you should actively seek medical advice.

Cough acid reflux

Weshor SeKaessner, a gastroenterologist at Queen Elizabeth Hospital in London, said that the main reason for waking up after coughing at night is acid reflux in the esophagus. Lying down after meals is easy to cause gastroesophageal reflux. Charles Murray, an expert in gastroenterology at Royal Free Hospital, said that excessive abdominal fat accumulation and excessive abdominal pressure are particularly likely to lead to acid reflux. Suggestion: It is best not to eat anything before going to bed, especially greasy food. In addition, blowing up the pillow also helps to prevent acid reflux.

Thirst-hyperglycemia or diabetes insipidus

Old thirst at night may be a symptom of diabetes insipidus. Due to the lack of antidiuretic hormone, patients can't adjust their body fluid levels, and their symptoms will get worse at night. Feeling thirsty after waking up may also be a symptom of uncontrolled diabetes, because high blood sugar levels can induce thirst. Other symptoms include emaciation, blurred vision and polyuria, especially at night. In addition, opening your mouth while sleeping can also lead to thirst after waking up. Suggestion: Go to the endocrinology department of the hospital for relevant examination. Headache-headache or bruxism. Headaches are more common in people over 50 years old. Headache attacks regularly every night, usually at 1 ~ 3 am. Dr Andy andy dawson, a headache expert at King's College Hospital, University of London, said that cluster headaches also occur regularly. Most patients are men, and they have pain in the back of one eye. Insufficient drinking water during the day can also lead to headaches at night. Dr. Dawson said that the dull pain in the chin after waking up may be caused by grinding your teeth at night. Grinding your teeth at night may also lead to earache and headache. Suggestion: Headache patients should go to the hospital, and it is best to wear mouthguard when sleeping at night.

Dizziness-ear infection

Ham Al-Ayoubi, an otolaryngologist at Chase Farm Hospital in London, said that he felt dizzy after waking up at night and the ceiling of the house was turning, so he might suffer from benign dizziness. Most patients are women over 50 years old. The cause is inflammation or infection that causes calcium carbonate crystals in the inner ear to fall off, and the balance system in the ear is disordered, which sends chaotic information to the brain, leading to dizziness. Suggestion: sleeping on your back and raising your pillow will help stabilize your head and prevent dizziness. Seriously, I have to go to the hospital for otolith reduction.

Half asleep-sleep apnea

Dr. Rousseau Foster, a professor of neuroscience at Oxford University and a sleep expert, said that some areas of the brain responsible for consciousness can still work in a shallow sleep state, even talking and getting up, but they are not fully awake and are in a state of half dream and half waking. If this happens frequently, it may be a manifestation of sleep problems such as sleep apnea. Suggestion: Losing weight, quitting smoking and drinking less can help to improve sleep apnea.

Frequent nightmares-side effects of drugs

Dr. Neil Stanley said that stress is the main cause of nightmares, and drugs such as antidepressants and beta blockers can also affect the natural sleep cycle and aggravate palpitation symptoms. Suggestion: relieve stress and find a doctor to adjust medication in time.

Night sweats-hormone disorder

Dr Declan Leah, a psychiatrist at a private psychiatric clinic in Kent, UK, said that people usually think that drinking alcohol before going to bed will help them sleep, but alcohol will dilate blood vessels in the skin and easily lead to sweating at night. In addition, the decrease of estrogen level in premenstrual, menstrual or postmenopausal women can also lead to night sweats. Dr Christopher Eaton, a urologist at the Royal Surrey Hospital, said that men's night sweats may be due to low levels of testosterone. Androgen plays an important role in controlling body temperature. Suggestion: drink less alcohol before going to bed and supplement hormones under the guidance of a doctor.

Back pain-inflammation or tumor

Physiotherapist Dr. Sammy margo said that if the mattress is too hard or too soft, it will easily lead to back pain. Arthritis patients may also wake up because of joint pain, because inflammatory chemicals in the human body are most active at night 1 1- 3 am. Lee Blackwell, a plastic surgery consultant at the Northern General Hospital in Sheffield, UK, said that if the pain intensifies at night and you wake up frequently, you may have discitis, which may be a bacterial infection or a tumor compressing the spine. Suggestion: the mattress should be replaced every 8~ 10 years. After lying down, the gap between the spine and the mattress is too large, indicating that the mattress is too hard; If you can't put it in your fingers, the mattress is too soft. Taking anti-inflammatory drugs before going to bed can help relieve the pain of arthritis patients.

Leg cramp-poor circulation of lower limbs

Dr Eddie Chalone, an expert in vascular surgery at Liu Yisham University Hospital in London, said that the main causes of leg muscle spasm at night include: 1. Problems with the blood circulation system. Peripheral vascular diseases and hyperlipidemia lead to thrombosis and partial occlusion of blood vessels. 2. Caused by pregnancy or excessive exercise. Both of these conditions will lead to the decrease of calcium and magnesium levels in the body, and calcium and magnesium are very important for muscle contraction and stretching. 3. Take statins and other drugs. A study in the United States found that statins increase the risk of muscle spasm by 20%. Suggestion: Stretching before going to bed, taking a hot bath and drinking a cup of warm water will all help to alleviate the problem of leg cramps at night.
