您的月经头晕吗？这是你的身体试图告诉你的

For many people with uteruses, a monthly menstrual cycle can be a source of discomfort and often come with a variety of symptoms.

人们在月经之前和期间报告的最常见症状是情绪变化，痉挛，疲劳和乳房敏感性。但事实证明，您还可以在期间遇到头晕的症状。

虽然短暂的头晕时刻通常不用担心，但月经期间的头晕咒语会感到不安甚至危险，尤其是当您开车或独自一人回家时。他们还可以指出一个基本问题，值得拜访医生。

Here, we spoke with ob-gyns to better understand what causes dizzy symptoms during your period and how to find relief.

Blood loss happens during menstruation. In fact, most people lose about 2 to 3 tablespoons of blood during their period, according toSomi Javaid, MD，由董事会认证的OB-GYN以及创始人兼首席医疗官HerMD。

While this amount isn't enough to cause dizziness, you can feel off balance if you have a heavier menstrual flow that results in贫血— a condition caused by a loss or lack of red blood cells that carry oxygen to the muscles in the body, per the梅奥诊所。

Javaid博士说：“当您患有大量月经出血的头晕时，氧气就会从大脑和肌肉中转移出来，头晕是您的大脑的“停止”信号，以试图将氧气恢复为大脑和肌肉。”

If your most-used item during your menstrual cycle is your加热垫, you might experience dizziness from the sudden onset of painful or intense cramps. It's possible to even醒来头晕从抽筋。

This is largely due to prostaglandins — hormone-like compounds that are primarily responsible for the uterine contractions you experience during menstruation, Dr. Javaid says.

"Prostaglandins, among other factors, are considered pro-inflammatory markers, meaning they play a role in the pain you experience with menstrual cramping," she says.

这些激素还会导致您的血管在月经期会显着膨胀，这可能会导致偶尔会出现令人头晕的发作，而痛苦的痛苦会使您感到头晕。

如果您的月经期间没有完全头晕，但在月经之前倾向于头昏眼花，那可能是由于激素水平的波动。

Javaid博士说，这是因为雌激素和孕激素（在我们的生殖和性健康中发挥作用的激素）会导致血糖水平的变化。

"These fluctuations may impact blood sugar levels, causing dizziness," she adds.

Dr. Danis also mentions that endocrine imbalances, such as thyroid disorders, ovulatory dysfunction or anovulation (when your ovaries don't release eggs during menstruation, per the克利夫兰诊所）也会影响激素水平，导致头晕和月经出血不规则。

Parents who breastfeed or胸饭丹尼斯博士说，他们的孩子还可以体验到激素催乳素的升高水平，这可能会引起头晕。胸部喂养也可能导致循环失调，这意味着您的流量可能较重，这会使您的脚上的脚步不那么坚固。

If your dizzy episodes don't seem connected to your blood sugar but rather a result of heavy bleeding, you may be experiencing子宫肌瘤（或肌瘤） - 由子宫中发育的平滑肌细胞制成的肿瘤，UCLA健康。这些肿瘤通常是良性且相当普遍的，一生中会影响70％至80％的子宫。

根据UCLA健康，子宫肌瘤的其他症状可能包括以下症状：

• 时期之间出血
• 骨盆疼痛和压力
• Frequent urination
• Low back pain
• 性交期间的疼痛

Similarly, you can get growths in your uterine lining called endometrial polyps, Dr. Danis says. "These arise from the overgrowth of the endometrial glandular tissue in your uterus," she adds. While these are also often benign, they can bleed.

这些生长所产生的痛苦和血液流失可能是您期间您可能会感到头晕和头晕的原因。

如果您最近决定获得植入节育的铜宫内节育器（最常见的品牌），丹尼斯博士说，您可能会注意到您在周期中释放出的血液量增加。

Indeed, a November 2018 review inPLOS One(which collected several study findings) discovered that increased bleeding and cramping during menstruation was the most common symptom reported after IUD insertion.

Some in the study even experienced bleeding throughout the entire month. While this is considered normal and will eventually lessen over time, the first few months can be a difficult transition as your body adjusts, especially if you're feeling dizzy.

您期间头晕的另一个原因？您可能只是累了。

Some people experience insomnia leading up to their period (a common symptom of premenstrual syndrome), per a February 2017 report in theJournal of Sleep Medicine and Disorders。So you may be due for some rest once your period arrives.

同样，丹尼斯博士说，由于荷尔蒙变化，人们在月经周期结束时也可能会感到更加疲倦。换句话说：从他们开始直到尾巴结束之前的一周开始，时期可能会使您感到疲倦，而且疲惫可能会导致头晕。

Javaid博士说，子宫患有子宫的患者可能会在其期间经历各种症状，但是任何新症状（例如那些被认为是“不寻常”的症状）应与您的OB-GYN或初级保健医生讨论。

It's worth noting, however, that occasional dizziness before and during your period is generally no cause for concern.

Javaid博士说：“如果头晕持续存在，就不会随着家庭干预的措施而改善，会干扰您的正常，日常活动，加剧或与极端疲劳和严重失血相结合，及时拜访您的医生。”
