The Hidden Impact of Low Blood Sugar on Mood Swings
Maintaining a stable blood sugar range is crucial for our overall well-being, and it's no secret that fluctuations can affect our mood. But what exactly happens when our blood sugar levels drop? How does this impact our mental health?
The Consequences of Dropped Blood Sugar: A Hormonal Imbalance When we eat a meal or snack, the carbohydrates in these foods are converted into glucose by the digestive system and absorbed into the bloodstream. This triggers an insulin response from the pancreas, which helps regulate blood sugar levels by facilitating its entry into cells for energy use. However, if our diet is high in refined sugars or low-fiber foods, it can cause a significant spike in blood glucose followed by a crash – leaving us feeling lethargic and irritable.
Why Mood Swings are Linked to Blood Sugar Fluctuations The brain relies heavily on glucose as its primary energy source. When we experience fluctuations in our blood sugar levels due to poor eating habits, stress or hormonal imbalances, it can have detrimental effects on cognitive function and mood regulation. Our brains go into 'crisis mode,' diverting all available resources to regulate the sudden drop – leaving us feeling anxious, depressed and irritable.
Insulin Resistance: A Key Player in Blood Sugar Fluctuations When we are constantly exposed to high levels of glucose due to poor diet choices or lack of physical activity, our cells become resistant to insulin. This leads to an overproduction of insulin by the pancreas, causing a rebound effect that drives blood sugar down too low for sustained energy production – exacerbating mood swings.
The Relationship Between Sleep and Blood Sugar Regulation During sleep, our bodies regulate their hormone levels to optimize various bodily functions. Poor-quality or insufficient sleep can disrupt this process leading to unstable blood sugar fluctuations throughout the day. Moreover, chronic stress that often accompanies lack of quality rest negatively impacts insulin sensitivity – further fueling mood disturbances.
Stress: The Unseen Driver Behind Blood Sugar Fluctuations Life is unpredictable and stressful situations are inevitable. What many people fail to realize is how deeply these periods affect their body's ability to regulate blood sugar levels, pushing it either upwards or downwards depending on the individual's coping mechanisms – ultimately contributing to an environment ripe for mood swings.
Managing Your Diet for a Healthy Blood Sugar Range Maintaining stable blood glucose through proper nutrition involves selecting whole foods like fruits, vegetables and lean protein sources that are low in glycemic index. These 'healthy' carbohydrates are gradually absorbed into our bloodstream without spiking blood sugar too high – creating an environment ideal for sustained energy production.
The Benefits of Increased Physical Activity on Blood Sugar Regulation Regular physical activity not only improves insulin sensitivity but also helps reduce inflammation and alleviate symptoms associated with stress such as depression and anxiety. While incorporating exercise is essential to a healthy lifestyle, finding the right balance between intensity and duration will help optimize its benefits without overexerting ourselves.
Why Stabilizing Your Blood Sugar Range Matters for Mental Health Maintaining optimal blood sugar levels may have an indirect effect on managing our mental state by mitigating depression symptoms. This direct link is due to reduced inflammation caused when glucose remains stable – allowing neurons to focus energy on producing neurotransmitters such as serotonin and dopamine which control mood regulation, appetite and other crucial functions.
Get my diabetes management guide here For those of you watching with diabetes, you probably know the answer to this question. But I have been asked with those with diabetes this question before. Hyperglycemia, high blood sugar or high blood glucose is the sign for all types of diabetes. The body can no longer regulate the blood sugar in your blood for one of two reasons: 1.The pancreas is no longer making enough insulin. 2.The body’s cells have become so resistant to insulin that the pancreas cannot keep up. Either way, the result is that glucose is accumulating in the bloodstream rather than being moved into the cells. But what does this feel like? How does your body react? Let me first say that you may feel some or all of the symptoms we blood sugar fluctuations in non diabetics discuss today. Hyperglycemia can affect different people in different ways, but there are some symptoms that are common among MOST people with diabetes. There are 3 most common and we will discuss those. But there are others. The most common signs of high blood sugar I call PolyCubed: . 1.Polyuria == This is excessive urination. You are constantly needing to run to the bathroom, like at least once an hour if not more often. This is caused by a dual chain reaction. The cells are pumping water into the bloodstream to try and dilute the glucose and bring it back to normal, and the kidneys, unable to reabsorb this fluid during filtering, are uncontrollably flushing water from the body. The result is runaway urination. 2.Polydipsia is the result of polyuria. It is excessive thirst. This is a response to the dehydrating effects of polyuria; it’s the body’s attempt to rehydrate itself. According to Wil Dubois BS, AAS, CPT, the relationship between excessive urination and excessive thirst is often misinterpreted by people experiencing high blood glucose, especially before diabetes is diagnosed. Many people assume that excessive urination is caused by the excessive 132 blood sugar before eating thirst and not the other way around. So they are quick to discount the excessive urination, thinking “Well, I’ve been drinking a lot lately…” 3.Polyphagia is the final main symptom of high blood glucose level. It is excessive hunger. It is not so much caused by the high blood glucose level as it is a low insulin level. the amount of insulin in the blood is insufficient to move glucose molecules from the bloodstream into the cells, where they can be used as fuel for cellular processes. If cells aren’t able to gain access to glucose, they send out hunger signals and the brain’s hypothalamus triggers the sensation of hunger. Those are the 3 main signs of high blood sugar. Most everyone who has a blood sugar level above 150 will experience one or all of these symptoms.Usually at least 2 of them. Another symptom you may feel is fatigue. Your body is working so hard to regulate your blood sugar and your cells can’t get the fuel they need to work properly. This will cause you to feel very tired. You will want to rest constantly. As the glucose levels rise in your blood stream, other symptoms are possible to appear. One that is very common of others I have talked to is blurred vision. Sometimes you see what I call “little snowmen” in your peripheral vision. This is the beginning of diabetic retinopathy. The tiny blood vessels in your eyes cannot carry the thicker blood causing oxygen levels in the optic nerve to drop. You may also experience one or more of the following after days of high blood glucose levels: Rapid, deep breathing. A fast heart rate and a weak pulse. A strong, fruity breath odor. Loss of appetite, belly pain, and/or vomiting. Lightheadedness. Headache Unexplained, rapid weight loss Tingling in hands and/or feet Scratches or sores that take a long time to heal It is difficult to answer what each individual will feel like when their blood sugar is high. It really depends on the individual and how high the blood glucose level is. Believe it or not, there are people who feel worse when their blood glucose levels are normal.They get used to how it feels to have elevated blood sugars and “normal” is not normal to them. If you experience any 2 of the PolyCubed symptoms and you have not been diagnosed with diabetes, you should get to your health care provider as soon as possible and ask them to check your blood glucose level. If you have diabetes and you experience any of the other symptoms, you need to make sure you keep a check on your blood sugar and if it remains high, see your health care provider and ask for an A1C test, this can help tell you how long your what range should my blood sugar be levels have been high. You may need to have your medication adjusted. High blood sugar is not something to just dismiss. It can have very serious consequences. If you even suspect you have high blood sugar, contact your health care provider.
