Unstable Blood Sugar Can Affect Your Mood?

Looking back, I have realized that a lot of my moodiness was probably caused by my uncontrolled blood sugars.

Are you aware that unstable blood sugar can cause you to suffer from depression and anxiety?

There is growing evidence that suggests that your blood sugar highs and lows can affect your mood. Irritability, anxiety and worry could closely mirror your blood sugar levels in light that your brain mainly runs on glucose.

About 25% of diabetics are currently affected by depression. Diabetics are more susceptible to pronounced blood sugar highs and lows and provide valuable insights.

A study found that inconsistent blood sugar levels among women with diabetes were associated with lower quality of life and negative moods.
Among diabetics, higher blood glucose or hyperglycemia has historically been associated with anger or sadness.
Blood sugar dips or hypoglycemia has been associated with nervousness.


Blood sugar fluctuations don’t just affect diabetics. Individuals consuming a diet high in refined carbohydrates and added sugars may experience a sudden surge in their blood sugar, followed by an exaggerated insulin response, leading to acute hypoglycemia.

A 2017 study found positive associations between high sugar consumption and common mental disorders, concluding that sugar intake from sweet foods and beverages has an adverse effect on long-term psychological health.


Before looking at medical treatment, it might be worthwhile to take a closer look at your diet and especially your sugar consumption.

Tips to help stabilize blood sugar

Reduce and manage stress
Stress can negatively affect the regulation of blood glucose. Specifically, hormonal changes during acute and chronic stress can affect your glucose balance.

Increase intake of protein and fiber
Protein has a low glycemic index (GI), which means that protein has a low impact on blood sugar levels. Fibrous foods are also shown to have a lower GI value when compared to their refined counterparts.

Reduce intake of sweet beverages and refined carbohydrates
A diet high in refined carbohydrates, including sweet beverages, has a high GI value and is associated with unstable blood sugar regulation.

More studies are needed to solidify the relationship between mood and blood sugar, but considering dietary and lifestyle implications on common mood disorders can rule out lesser-known causes.
