Welcome to 

Environmental Health Center!

Welcome to our home page, where we empower individuals to address the root cause of their health issues and embark on a journey towards a symptom-free and medicine-free life.

Are you feeling tired, experiencing headaches, or grappling with other persistent symptoms that seem unresolvable? Look no further – we are here to assist you.

Are you ready to put an end to your suffering? It’s time to treat the cause of your health concerns. Remember, you are free to make choices, but you are not free from the consequences of those choices.

You may have already tried various medical approaches and medications without finding lasting relief. The reason might be that you’ve only explored the first option – treating symptoms with medicines. We want to introduce you to the second option – treating the cause.

Here are the two options explained:

1. Treat symptoms with medicines: This approach offers temporary relief but does not address the root cause and may come with unwanted side effects.

2. Treat the cause (A Different Approach): Many people are unaware of this option’s existence. Our mission is to educate you about this approach, which holds the key to resolving your health issues. The information provided here and, in the links below will shed light on this alternative method, helping you understand the significance of treating the cause.

As a medical professional with 44 years of experience, I was initially unaware of this second option until I discovered Functional Medicine. Now, I want to share this knowledge with you. See my story here, DR. SULTAN’S STORY

So, what’s the solution? You need a physician well-versed in Functional Medicine, someone who will not merely prescribe medications to mask symptoms. You deserve a healthcare partner who will take the time to listen, conduct appropriate tests, identify the underlying causes, and guide you in treating them effectively.

The benefits of treating the cause are numerous. By addressing the root issues, we can help you eliminate symptoms, reduce dependency on medications, and experience genuine relief. This approach can also significantly reduce your medical expenses, making good health more affordable.

Remember, most chronic illnesses have identifiable causes, such as environmental factors (what you eat, drink, breathe, and touch), nutritional imbalances, hormonal issues, and dietary habits. Unfortunately, these aspects often receive insufficient attention in the conventional medical community, leading to continued suffering for many individuals.

If you seek better health and true wellness, give us a call, and we will work together to identify the appropriate causes and provide the best possible care.
