Quick answer: People often consider detox support when they notice ongoing fatigue, brain fog, headaches, aches, skin problems, digestive issues, frequent colds, hormone changes, food or chemical sensitivities, weight changes or mood swings. These symptoms have many possible causes, so it’s important to see a provider to rule out other conditions before assuming toxins are to blame.
Key takeaways
Ongoing fatigue, brain fog, headaches, aches, skin problems and digestive changes are often listed as signs the body could use more support.
These symptoms are common and nonspecific, so thyroid problems, anemia, sleep apnea, depression and other causes are worth ruling out first.
Once other causes are checked, whole foods, hydration, good sleep and fewer everyday exposures are gentle places to start.
Common signs
- Ongoing fatigue or low energy

Rule out other causes first
These symptoms are common and nonspecific. Thyroid problems, anemia, sleep apnea, depression and many other conditions can cause them. See your provider first. Useful labs: TSH and ferritin.
Supporting your body
If other causes are ruled out, focusing on whole foods, hydration, sleep and fewer exposures can help. Start with the 14-Day Detox or how detoxification works.
Healthy aging lens
Persistent fatigue and inflammation are worth investigating at any age; addressing root causes early may support healthy aging.
When to see a naturopathic doctor
It may be time to see a naturopathic doctor if you have ongoing fatigue, headaches, skin or digestive symptoms, or known exposure to lead, mercury, mold or workplace chemicals. The same is true if you take medications or have liver, kidney or heart conditions and want to try a detox plan, or if you are pregnant or breastfeeding (detox protocols are not recommended).
See a medical provider promptly for signs of poisoning such as severe abdominal pain, vomiting, confusion, seizures or trouble breathing, or call Poison Control at 1-800-222-1222.
