Sometimes relatively simple changes can radically improve a patient’s health!”
After a thorough physical examination, targeted blood work and other specialized tests to find hormonal imbalances, nutritional deficiencies, or other fundamental dysfunctions within the body will be ordered.

Tired vs. Exhausted: How to Tell When Fatigue Needs More Attention
/in Chronic Fatigue/by Kaplan CenterFeeling tired is a common experience for many of us. We often brush it off as a result of a long day at work, a busy schedule, or simply not getting enough sleep. How do you know when your tiredness is just a normal part of life and when it might be a sign of something more serious, like Chronic Fatigue Syndrome (CFS)? Understanding the difference can help you manage your energy better and know when to seek professional help.
Everyday Tiredness: What’s Normal?
Everyday tiredness is something most people experience from time to time. It typically results from various factors that can be addressed with simple lifestyle changes. Here’s a deeper look into common causes:
Chronic Fatigue Syndrome: When Fatigue Isn’t Just Fatigue
Chronic Fatigue Syndrome (CFS), also known as myalgic encephalomyelitis (ME), is a complex, multi-system disease characterized by severe, persistent fatigue that doesn’t improve with rest and often worsens with physical or mental exertion. There is no specific known cause of CFS, but research points to inflammation of the central nervous system, which in turn can cause a wide range of debilitating symptoms.
The following is a more detailed look into the symptoms and features of CFS:
Diagnosing Chronic Fatigue Syndrome
Diagnosing CFS can be challenging because there is no specific test for it. Healthcare providers typically diagnose CFS based on a combination of symptoms, medical history and ruling out other conditions that could cause similar symptoms. A thorough evaluation may include:
Managing Fatigue and Improving Your Well-Being
Regardless of whether you’re dealing with everyday tiredness or CFS, there are steps you can take, and services available that can help you manage fatigue and improve your overall well-being:
When to Seek Medical Advice
Seeking medical advice is crucial if you suspect your fatigue might be more than just everyday tiredness. If you have prolonged fatigue or unexplained and persistent symptoms and your fatigue is impacting your daily life, please give us a call. While everyday fatigue can often be addressed with lifestyle adjustments, persistent and severe fatigue may indicate a more serious condition that requires professional attention.

Top 6 Food Types to Clear Your Brain Fog and Boost Your Cognitive Function
/in Digestive Issues, Long Covid, Nutrition, Wellness/by Gary Kaplan, DODo you often experience brain fog? It’s that feeling of mental fatigue that drains your energy, causes poor concentration, and prevents you from gathering your thoughts. I’m sure that many of you can relate to that. Actually, brain fog is a common trend in our modern society. It may occur as a symptom of an underlying illness, side-effects from medication, hidden allergies (e.g. gluten), lack of sleep, dehydration, and even over-eating (i.e. eating too many calories).
However, brain fog is not a medical diagnosis, but a set of subjective symptoms that people experience and describe as:
The good news is that there are small tweaks that can be done nutritionally to help clear brain fog, boost energy, and increase productivity. The key is keeping your brain well-fed, nourished, and oxygenated.
1. Drink Up! Water is the way to go.
Water is vital to the proper functioning of human cells and our body systems; it accounts for 60% to 70% of total body weight in lean adults, and 45% to 55% in obese adults. Water plays a major role in brain function; approximately 75% of the processes that take place in the brain occur in the presence of water!
Drinking adequate amounts of water will help increase mental clarity and concentration, help prevent headaches, and help in the removal of toxins and cellular waste that accumulate in the blood and travel to the brain.
How much should you drink? A simple way to calculate your daily water requirement is by dividing your body weight in half and replacing pounds with ounces. So if you weigh 140 lbs., your water requirement is 70 oz. There are two other factors to keep in mind, and the first is physical activity; athletes and active people need more water than sedentary people. The second factor is the weather; during the hot summer months, you need to boost up your water intake even more.
2. Brain Fuel: Omega 3’s
Omega 3s are the most preferred “essential” nutrient to the brain and nervous system. They are called essential because our body does not make them, so we need to get them from our diet.
Among their infinite benefits, omega 3s lower inflammation, protect cell membranes, improve cognition and memory, and improve mood stability.
What to eat: The best sources of omega 3 are fatty fish (salmon, trout, cod liver, herring, mackerel, and sardines), shellfish (shrimp, oysters, clams, and scallops), or krill oil. You may also get omega 3s from plant-based foods, such as flaxseed, chia seeds, or walnuts, however, their conversion to the absorbable form, known as EPA and DHA, is very low – between 5% – 10%.

3. Rainbow foods: Flavonoids
Flavonoids are plant-derived compounds that have antioxidant properties. They scavenge harmful toxic cellular wastes in the body called “free radicals.” Free radicals damage brain cells and DNA through a process called oxidation, which contributes to brain fog related symptoms.
Studies indicate that flavonoids found in certain fruits and veggies are able to improve memory and brain function, thereby helping to lower symptoms related to brain fog.
Fruits like grapes, pomegranates, strawberries, and blueberries have shown to improve many aspects of memory and learning, such as: rapid and slow memory acquisition, short-term working memory, long-term reference memory, and memory retention and retrieval.
What to eat: Lots of fruits and vegetables! Go for a rainbow of color.
4. Quercetin-rich foods
Quercetin is a flavonol (a subtype of flavonoids) found in plants and known for its antioxidant properties.
Unique to quercetin is its ability to block histamine release, the main trigger for allergies which can cause symptoms of brain fog.
What to eat: Foods that are rich in quercetin are: ancho peppers, red onions, dill weed, cranberries, and buckwheat.
5. Brain Treat: Dark Chocolate
In addition to being delicious, DARK chocolate is a superfood, which means it’s a highly potent antioxidant and brain booster. Cocoa flavonols, which are the active compounds in the cocoa powder found in chocolate, have been shown to increase blood flow to the brain, providing it with an abundant supply of nutrients and oxygen.
Studies have shown cocoa flavonols improve cognitive function and blood pressure control in older adults, improve concentration, and can help stabilize mood.
What to eat: When buying a chocolate bar, the darker the chocolate, the better (look for 70% or more cacao* content). You can also buy good quality, dark chocolate cocoa powder, but you’ll notice it can be bitter, so a great way of getting it in your diet is by adding it to your smoothies.
* Cocoa powder comes from raw cacao that has been roasted at high temperatures.
6. Happy Brain = Happy gut: Probiotic-rich foods
The human body carries over 100 trillion bacteria in the gut, outweighing the human body’s cells! These bacteria work synergistically with the body’s systems and contribute to the synthesis of vitamins and neurotransmitters (brain chemicals), and also help with food digestion.
The gut also hosts harmful bacteria, but in smaller amounts. These opportunistic species thrive on sugars, which can lead to overgrowth and create an imbalance in the microbiome. The connection between the brain and gut is bi-directional, which means if one consumes a high processed meal that is loaded with simple sugars, the brain will suffer from a lack of neurotransmitters and vital nutrients. This leads to brain fog symptoms and potentially other serious conditions. So basically, food choices and a clean diet are tremendous for brain health.
What to eat: Incorporating probiotic-rich food in your diet will help balance gut flora and get rid of harmful bacteria. These foods are Sauerkraut, kimchi, Kombucha (watch out for sugar content), and kefir. Supplementing with probiotics is another great way to get good bacteria into your diet.
