什么是排尿过多?
当您的排尿多于正常水平时,会出现过多的排尿体积(或多尿液)。如果每天等于2.5升,则认为尿量过多。
“正常”尿量取决于您的年龄和性别。但是,每天少于2升通常被认为是正常的。
排泄尿液量过多是一种常见的condition but should not last more than several days. Many people notice the symptom at night. In this case, it is called nocturnal polyuria (or nocturia).
Excessive urine output can sometimes signal health problems, including:
- bladder infection (common in children and women)
- urinary incontinence
- 糖尿病
- 间质性肾炎
- 肾功能衰竭
- kidney stones
- 心理多养生,一种精神障碍,导致口渴过度
- 镰状细胞性贫血
- 扩大前列腺,也称为良性前列腺增生症(在50岁以上的男性中最常见)
- 某些类型的癌症
您也可能会注意到CT扫描或任何其他医院测试后,将染料注入体内。测试后一天,过量的尿量很常见。如果问题持续下去,请致电您的医生。
Excessive urine volume often occurs due to lifestyle behaviors. This can include drinking large amounts of liquid, which is known as polydipsia and isn’t a serious health concern. Drinking alcohol and caffeine can also lead to polyuria.
Certain medications, such as diuretics, increase urine volume. Talk to your doctor if you recently started a new medication (or just changed your dosage) and notice changes in your urine volume. Both alcohol and caffeine are diuretics, and some medications for high blood pressure and edema also act as diuretics, including:
- 噻嗪类利尿剂,例如氯噻嗪和氢氯噻嗪
- potassium-sparing diuretics, such as eplerenone and triamterene
- 循环利尿剂,例如弹甲酰胺和速尿
您可能会体验多尿作为这些药物的副作用。
Seek treatment for polyuria if you think a health issue is the cause. Certain symptoms should prompt you to see your doctor right away, including:
- 发烧
- 背疼
- leg weakness
- sudden onset of polyuria, especially in early childhood
- 精神错乱
- night sweats
- weight loss
These symptoms can signal spinal cord disorders, diabetes, kidney infections, or cancer. Seek treatment as soon as you notice these symptoms. Treatment can help you quickly address the cause of your polyuria and maintain good health.
If you think the increase is due to an increase in fluids or medication, monitor your urine volume for a couple of days. If the excessive volume continues after this period of monitoring, talk to your doctor.
糖尿病mellitus (often simply called diabetes) is one of the most common causes of polyuria. In this condition, high amounts of glucose (blood sugar) collect in your kidney tubules and cause your urine volume to increase.
糖尿病的另一种形式称为糖尿病,因为您的身体没有产生足够的抗利尿激素,因此增加了尿量。抗利尿激素也称为ADH或加压素。ADH是由您的垂体产生的,是肾脏中液体吸收过程的一部分。如果没有足够的ADH,您的尿量可能会增加。如果您的肾脏无法正确控制通过它们的液体,它也会增加。这被称为肾脏基糖尿病。
如果您的医生怀疑糖尿病会导致您的多尿症,您的血糖将测量您的血糖。如果一种糖尿病形式引起多尿,您的医生将建议您改善治疗和生活方式,以帮助您控制糖尿病。这些治疗方法可以包括:
- 胰岛素注射
- oral medications
- 饮食变化
- 锻炼
可以在家中解决并非基本健康问题引起的尿量过多。
您可能可以通过简单地改变导致尿量过大的行为来缓解症状。尝试以下提示:
- 观察您的液体摄入量。
- 就寝前限制液体。
- 限制咖啡因和酒精饮料。
- 了解药物的副作用。
Excessive urine volume caused by health concerns, such as diabetes, can be addressed by treating the underlying cause. For example, treatment for diabetes through changes in diet and medication often relieve the side effect of excessive urine volume.
与您的医生诚实和诚实有关排尿过多的问题。与您的医生谈论您的排尿习惯可能会感到不舒服。但是,多尿的前景通常很好,尤其是如果您没有任何严重的医疗状况。您可能只需要改变生活方式即可解决多尿。
Other underlying conditions causing polyuria may require extensive or long-term treatment. If diabetes or cancer is causing polyuria, your doctor will discuss the necessary treatments for resolving any medical issues in addition to helping get your polyuria under control.
