Brain Fog: 6 Causes – Health Fitness

What is brain fog?

Brain fog is not a medical condition in itself. It’s a sign of other medical conditions. It is a form of cognitive dysfunction that involves:

  • Memory problems
  • Lack of mental clarity
  • poor concentration
  • Inability to focus

It can also be called mental fatigue and can affect your ability to work or school depending on how severe it is. There is no need to be a permanent fixture in your life.

Brain fog can be caused by many factors. You can fix the problem once you have identified the root cause. These are six possible causes.

This amazing food is from where? It hails from Ilocos, the northern region in the Philippines. Spanish introduced the technique for sauteing foods to Ilocano cuisine during Spanish rule. This same technique is used in our Igado.

Hormone imbalances

The baby brain is a real thing, especially in the first half of a woman’s pregnancy. Expectant mothers can forgetfulness due to hormonal changes during pregnancy. High levels of estrogen and progesterone can cause short-term memory problems.

Hormonal imbalances can occur regardless of sex and life stage. Menopause can lead to memory problems and cloudy-headedness due to estrogen decreasing. Mental fatigue can be caused by a low testosterone level in men at any age.

Mind haze can likewise be caused by thyroid issues.

Thyroid hormones are directly connected to the brain to regulate energy, metabolism, and executive function. Both hypo- and hyperthyroid can cause memory problems.

What should I do?

Check your hormone levels. Thorne offers two at-home tests – Fertility, and Thyroid. These tests measure hormones. The results will help you to understand how your lifestyle and diet affect them.


Chronic stress can cause high blood pressure, depression, and weaken immunity. Mental fatigue can also be caused by chronic stress. It can make it difficult to think, reason, or focus when your brain is tired.

Sleep deprivation

Bad sleep quality can also affect how your brain functions. You should aim for between 8 and 9 hours of sleep each night. Too little sleep can cause poor concentration and cloudy thinking.

Hormonal changes

Brain fog can also be caused by hormonal changes. During pregnancy, estrogen and progesterone levels increase. This can cause memory loss and short-term cognitive impairment.

A drop in estrogen levels during menopause could likewise cause absent-mindedness, helpless fixation, and shady reasoning.

Prescription medicines

The brain’s parts that make short-term memories long-term memory are directly affected by benzodiazepines. Statin drugs lower cholesterol in all parts of the body, including the brain. This is where cholesterol is required for nerve cell connections.

Narcotic painkillers alter chemical signals that are associated with cognition. To treat hypertension, beta-blockers also block chemical messages in brains such as neurotransmitters. Nonbenzodiazepine-sedative-hypnotics can be prescribed for sleep and may act on the same brain pathways as benzodiazepines.

Some sleep aids can cause amnesia, which can sometimes lead to dangerous or unusual behaviors such as driving a car or cooking a meal without any recollection of doing it when you wake up.

Chronic diseases

A viral, fungal, or bacterial infection could cause you to experience brain fog. Overgrowth of Candida yeast, which occurs naturally in the body, is one of the most common lingering infections.

Candida is a fungus found in the mouth and gut. Candida is a fungus that hides in your mouth and gut.

Miscommunications can cause memory impairments because your gut communicates directly to your brain.


Brain fog can also be caused by diet. Vitamin B-12 is essential for healthy brain function. A vitamin B-12 insufficient could cause brain fog.

Brain fog can occur after you eat certain foods if you have allergies or sensitivities. These could be the culprits:

  • Aspartame
  • peanuts
  • dairy

You can reduce symptoms by removing trigger foods.

Medical conditions

Mental fatigue can also be caused by medical conditions such as fatigue, inflammation, and changes in blood glucose levels. Brain fog, for example, is a sign of chronic fatigue syndrome. This is where you feel persistent fatigue for more than six months.

Fibromyalgia sufferers may experience similar symptoms on a daily basis.

Brain fog can also be caused by:

  • anemia
  • Depression
  • diabetes
  • Sjogren syndrome
  • Migraines
  • Alzheimer’s Disease
  • hypothyroidism
  • Autoimmune diseases like Lupus and arthritis. Multiple Sclerosis.
  • Dehydration

How it diagnoses

Brain Fog: 6 Causes - Health Fitness

If you experience persistent confusion that doesn’t get better, consult your doctor. A single test can’t diagnose brain fog. Your doctor may order a physical exam to determine if brain fog is a sign of an underlying problem.

  • Mental health
  • diet
  • Level of physical activity
  • Current medications and supplements

Your doctor should be notified of any other symptoms. Hypothyroidism can cause brain fog, hair loss, dry skin and weight gain.

Your doctor can diagnose brain fog by performing a blood test.

Blood Test diagnoses the following:

  • abnormal glucose levels
  • Poor liver, thyroid, and kidney function
  • nutritional deficiencies
  • Infections
  • Inflammatory diseases

Your doctor will decide whether further investigation is necessary based on the results. Imaging tests that look inside the body may also be used to diagnose problems, such as MRIs, X-rays, and CT scans. A doctor might also perform allergy testing or a sleeping study to determine if there is a sleep disorder.

How to deal with it

Treatment of brain fog depends on the cause.

Iron supplements can increase the production of red blood cells in anemic patients. This may reduce brain fog. Your doctor might recommend medication or corticosteroids to lower inflammation or suppress the immune response if you have an autoimmune disorder.

Sometimes, brain fog can be treated by changing medications or correcting nutritional deficiencies.

These are some home remedies that can improve brain fog:

  • Sleeping 8-9 hours per night
  • Stress management is about knowing your limits and avoiding excessive alcohol or caffeine
  • exercising
  • You can increase your brain power by volunteering or solving brain puzzles.
  • Find fun activities
  • Increasing your intake of fruits and vegetables, protein, and healthy fats
