Find Out What Your Irregular Periods Could Mean

So many things can affect your cycle, from your stress level to a potential physical anomaly inside that you’re not aware of. Let’s see what your answers tell us. 

If your answers are mostly A’s: You might be experiencing temporary irregularity  

You may be experiencing some hormonal changes that are causing your irregular periods. This can happen in early puberty, for example, when your body is still adjusting. Or if you are in your forties to early fifties, and experiencing other symptoms of perimenopause or menopause.

In early pregnancy, your body may take time to stop menstruating. On the other hand, if you’re trying to prevent pregnancy by using hormonal birth control methods such as the pill, patch, or hormonal IUD, your irregular periods could be a sign that your body is slowly adjusting to the synthetic hormones. 

Lifestyle can be a factor too. High stress increases cortisol, which can cause certain parts of your body like your reproductive system to stop working. Once your stress level stabilises, your period may go back to its normal cycle. 

If your answers are mostly B’s and C’s: You might have hormonal imbalance that requires medical evaluation 

If your irregular periods are accompanied by other risk factors and you can’t seem to get a sense of normalcy, then you could have one or more medical conditions – such as hormonal imbalance.

Hormonal imbalance is when the ovaries produce an excess of male (androgen) hormones and can prevent ovulation during each menstrual cycle. Another condition associated with hormone imbalance – specifically oestrogen dominance and progesterone resistance – is endometriosis where cells that normally grow on the uterine lining (endometrium) are found outside of the uterus. This condition causes heavy and prolonged bleeding as well as extreme pain during menstruation.

Uterine fibroids and uterine polyps are also associated with oestrogen dominance, and can cause irregular periods and difficulty in conceiving. Treatment for these conditions may include hormone treatments to address the specific hormonal imbalance. 

The TCM Perspective on Hormonal Imbalance

Angelica sinensis (dong quai, 当归) is a common TCM herb used to treat hormonal imbalance.

In Traditional Chinese Medicine (TCM), hormonal imbalances that lead to irregular periods could be caused by three conditions: Kidney Deficiency, Spleen Deficiency, or Liver Stagnation.

“The Kidney’s qi (vital energy) and jing (essence) are the roots of a woman’s period and her reproductive system,” TCM physician Ho Li Ying explains. A deficiency in the Kidney can directly affect her period. Overworking, excessive sex, staying up late – these contribute to a Kidney qi Deficiency. Symptoms may include lower back pain, especially before or during periods, hypomenorrhea, light red menstrual blood, tinnitus, dizziness, and nocturia. 

“Meanwhile Deficiency in Spleen causes Phlegm-Dampness, slow metabolism, and Stagnation of qi and blood, as well as Deficiency in qi and blood,” she further elaborates. An erratic diet such as consuming excessive cold or oily food and drinks, overworking and emotional imbalances such as anxiety and overthinking can all lead to Deficiency in Spleen. Symptoms include tiredness, dizziness, hypermenorrhea, and loose stools, with a tendency to either gain weight easily or being underweight. 

“Liver Stagnation is mainly affected by emotions such as anger, depression, or stress. These emotions cause Stagnation in the Liver qi, affecting qi and blood circulation, resulting in irregular periods,” Physician Ho explains. Other symptoms include period pain, delayed menstruation, insomnia, bloating in stomach or abdomen, headache, or breast tenderness especially before the period. 

How TCM Corrects Hormonal Imbalance 

Bak foong pill is a TCM formulation aimed at improving Kidney and Spleen, as well as qi and blood. It has been shown to effectively reduce excessive male hormones when used with metformin in animal models. TCM formulations containing herbs such as Radix Angelica sinensis, Rhizoma chuanxiong, and Fructus Jujubae are known to help menstrual blood flow. They can also be found in easy-to-consume supplement drinks.

While studies are still ongoing regarding the exact mechanism of acupuncture, some show that acupuncture is associated with hormonal changes in treating menstrual disorders. To further promote hormonal balance, Physician Ho recommends the following: 

  • Practice a balanced diet  
  • Avoid cold food and drinks 
  • Maintain healthy sleep (go to bed before 11pm) 
  • Exercise regularly 
  • Manage stress levels and bad emotions 

Hormonal balance is a key aspect of everyone’s health, especially for women as hormones govern their reproductive system. It helps to know whether your irregular period is temporary and can be addressed by changing your lifestyle choices, or whether you should go for further medical evaluation to rule out more serious illnesses.
