What day is it?

Did I send that mail to the client?

Why did I come upstairs to this room?

Oh no! I forgot to log out of the system.

What’s the name of that tall, blonde woman in the movie?”

It is just 11 am on Monday, and you are already tired or sleeping, unable to concentrate, and thoughts cascading and confusing your mind. You feel that your mind has turned into a fuzzy cotton ball. Worse, someone has tried to make a puree of your brain while leaving it halfway through the process.

Well, these symptoms could be an indication of brain fog, which happens to all of us. It wouldn’t be wrong to say that it makes us feel like a ‘windows 95 os trying to play a 4k video’.

The foggy feeling will make it difficult to get through the day, even if you are healthy physically. And you may have tried different things to get over it, from iced coffee to taking a nap.

Yet, you never felt quite refreshed.

Do you know what they say? To battle against this sluggish feeling, you must know the root cause of the ailment. Well, let’s focus on that.

There are various potential causes for brain fog – and would you believe if we say blood sugar level could be a reason? Yes, it is.

So, without further ado, let us take an insight into the connection between diabetes and brain fog.

What is Brain Fog?

Brain fog, defined as mental fuzziness, is closely related to mental health and impacts your daily activities. The unpredictable nature of the condition might also induce anxiety, depression, fear, or stress.

Simply put, it is a general term to explain a broad range of symptoms affecting memory, attention, learning, mental clarity, and other executive functions.

When the symptoms of brain fog are left unnoticed, it will interfere with the quality of your life in no time.

Can Diabetes Cause Brain Fog?

Diabetes mellitus is a chronic condition that causes brain fog and even other conditions such as mood swings, irritation, or cravings throughout the day. The relationship between diabetes and brain fog has to be explored completely, as it is imperative to a healthy brain and overall well-being.

In diabetes, blood sugar regulation has vital implications on how you feel and function daily. If you are experiencing brain fog, it may result from blood sugar dysregulation. Abnormal or sudden changes in the blood glucose level can happen anytime and is completely normal. However, large spikes followed by sudden drips can cause harm to one’s health.

Furthermore, diabetes affects the tiny blood vessels and decreases the supply of oxygen and nutrients to the brain. It might also result in mental fogginess.

Who is Prone to Brain Fog?

Anyone with the following are prone to Brain Fog:

  1. uncontrolled blood sugar levels
  2. low blood sugar levels
  3. fluctuating blood sugar levels
  4. high stress
  5. older aged people
  6. someone with a history of Alzheimer’s or Dementia

Causes of Brain Fog in Diabetes

If you think diabetes is the only culprit behind brain fog, then it’s time to explore other underlying causes.

1) High Blood Pressure

Stress or excess mental pressure can spike blood pressure levels and impact the function of the immune system, leading to mental fatigue. It will profoundly exhaust your brain, making it hard to think or focus on activities.

2) Poor Sleep Regime

Our brain’s normal functioning is disrupted when we are deprived of sleep. Conventional wisdom says we must sleep 6-8 hours daily. Sadly, we don’t follow it. Anyway, the bottom line is that poor sleeping patterns will lead to poor concentration and cloud the thoughts in your brain.

3) Age and neurodegenerative conditions

The risk of brain fog increases with advancing age. Typically, an individual will have foggy thoughts between 40 and 80 years of age. Elderly people with brian fog may be associated with Alzheimer’s disease or any other form of dementia.

4) Hormonal Imbalance

An increase in hormones, estrogen and progesterone, might cause short-term brain fog, especially during pregnancy. Similarly, a drop in the estrogen level during menopause will cause sudden sweating, forgetfulness, cloudy thoughts, poor focus, and hot flashes.

5) Deficiency/Allergies

Vitamin B12 deficiency is another primary cause of brain fog. Furthermore, if you have food allergies or sensitivities, certain food like dairy products or peanuts can induce brain fog.

Symptoms of Brain Fog in Diabetes

You can identify brain fog in diabetes if you have the following symptoms,

  • Mental fatigue
  • Forgetfulness
  • Irritability
  • Lack of clarity in thoughts
  • Inability to concentrate or focus
  • A decreased span of attention
  • Inability to multitask
  • Difficulty in processing even simple information
  • Persistent feelings of confusion or being disorganised

What are the Treatment Options?

The good news is that brain fog in diabetes is treatable. These are the things you can do:

  1. Find the exact cause
  2. Control your sugar levels
  3. Healthy eating
  4. Sleep/stress management
  5. Exercise
  6. Consult your doctor immediately

Now let’s elaborate this a bit.

1) Consultation with your physician

The key to effective treatment is to know the exact underlying cause of the condition. Your doctor will work closely with you to get to the root cause and resolve brain fog over time. They will craft a personalized treatment approach to address the symptoms you are experiencing and get rid of the issue.

2) Contemplate the Content on Your Plate

Mental clarity and healthy blood sugar are related to a happy gut. Therefore, fill your plate with foods rich in fiber, iron, and antioxidants. Consume Vitamin B12-rich eggs, dairy, meat, mushrooms, and fish. Try to snack on dry fruits like almonds and avoid refined sugar or fried foods, as they can harm your blood sugar and brain health.

Opting for a diabetes management program will allow you to include a healthy diet balanced with micro and macronutrients while you can relish your favorite dish occasionally.

3) Take a Walk on the Way

In the beginning, taking 10,000 steps a day might be overwhelming. Hence, start with 4000 steps of daily movement for healthy brain tissue and ideal blood sugar management. It is especially relevant for memory and overall cognitive functions. You can use our diabetes weight loss plan to create a custom-made experience program to achieve your goal.

4) Prioritize Your Sleep Pattern

When we rest, our body parts feel relaxed. Similarly, our brain must be well-rested to function healthily the next day. Sleep helps you to reset your body. And when you lack quality sleep, the persistent brain fog will readily add up. Experts advise taking 7-8 hours of quality sleep. If you are struggling, you can use aromatherapy or other relaxing aids.

5) Stress management

Being stressed for a long time will induce brain fog, poor decision making and memory loss. To overcome the challenge, you can implement stress management techniques like meditation to deal with stressful situations. They will make you smarter, happier and healthier, as well as resilient towards the ups and downs of your life.

Can It Be Prevented?
