You felt fine at home. But since moving to Dubai — or since your lifestyle here shifted significantly — things have changed. Your cycle is different. Your energy is less predictable. Your mood, weight, or skin have changed in ways you didn’t expect. And nobody has offered an explanation that makes sense.
The good news: research has found clear reasons why relocation involves a hormonal adjustment period — and there is a lot you can do to support your body through it so you can feel well here.
As a CNM Qualified Naturopathic Health Coach in Dubai, KHDA approved and trained at the College of Naturopathic Medicine, I work with women navigating exactly this picture. Here is what studies have found.
What Research Shows About the Body’s Response to Relocation
Moving country is not just a logistical event — research has consistently found it is a significant physiological one too.
A study published in the International Journal of Environmental Research and Public Health found that international relocation was associated with measurable changes in stress hormones, immune function, and gut bacteria composition within the first few months of arrival. The researchers noted that even positive, chosen moves produced these physiological responses — because the body responds to change and adjustment, regardless of whether the mind welcomes the move.
Research on expat health consistently shows higher rates of reported stress, disrupted sleep, and hormonal symptoms in the first one to three years after relocation compared to pre-move levels. Studies suggest the body needs time to settle — and that certain systems, including the hormonal system, are more sensitive to this adjustment than others.
The Stress-Hormone Connection Research Has Found
When the body is adapting to a new country — building new routines, establishing new social connections, and adjusting to a different environment — research has found it affects the hormonal system in specific ways.
Studies have found that prolonged stress affects the balance between the body’s stress hormones and reproductive hormones. Research published in the journal Fertility and Sterility has found associations between chronic stress and changes to the menstrual cycle — including irregular or missed periods, heavier or lighter bleeding, and changes to cycle length — in women who do not have any underlying reproductive condition.
Research has also found that sustained stress can affect progesterone levels specifically — the hormone responsible for the second half of the menstrual cycle. Studies suggest lower progesterone relative to oestrogen is associated with premenstrual symptoms, sleep disruption, mood changes, and weight retention.
The Vitamin D Opportunity in Dubai
Research has found a link between vitamin D levels and hormonal health — and in Dubai, checking and optimising your vitamin D is one of the most straightforward and affordable health steps available.
Studies have found associations between low vitamin D and disrupted menstrual cycles, worsening PMS, reduced fertility markers, and thyroid changes. A study published in the European Journal of Endocrinology found that women with vitamin D deficiency showed differences in hormone levels compared to those with adequate levels, and that supplementation was associated with improvements in cycle regularity in some groups.
Research shows that women who spend most of their time indoors — in air-conditioned offices, cars, and homes — can have lower vitamin D levels regardless of how sunny their environment is. The great news for women in Dubai is that testing is simple, quick, and inexpensive here — and if levels are low, supplementation is very effective. This is one of the easiest wins for hormonal health in the UAE.
Gut Changes After Moving and Their Hormonal Effects
Research on gut bacteria has found that the gut microbiome changes significantly within weeks of moving to a new country — responding to the new food environment, water supply, stress levels, and bacterial exposures.
This matters for hormonal health because research has found that gut bacteria play a role in how the body processes and recycles hormones — particularly oestrogen. Studies have identified a group of gut bacteria researchers call the “estrobolome” — bacteria that influence how oestrogen is metabolised and eliminated from the body. When gut bacteria are disrupted, research suggests oestrogen processing changes — which can contribute to hormonal imbalance symptoms.
What Research Suggests Helps
Get your vitamin D tested. Research is clear that this is one of the most impactful and most commonly missed nutritional factors affecting hormonal health. In Dubai, a blood test is quick and affordable — and if levels are low, supplementation under guidance is straightforward and effective.
Support gut recovery. Research on gut bacteria recovery points to consistent fermented foods and plant variety as the most effective dietary approaches. Given the research on gut bacteria and hormonal processing, this is directly relevant to hormonal balance too.
Prioritise settling your sleep routine. Research on people who have changed time zones significantly shows that sleep disruption has measurable effects on hormonal rhythms. Studies suggest establishing a consistent sleep schedule as early as possible after a move supports hormonal recovery.
Give yourself time — with support. Research consistently shows that the adjustment after relocation has a biological timeline. Studies suggest most physiological markers return closer to baseline within one to two years — and this is supported, not just endured, through deliberate nutritional and lifestyle choices.

One thing you can do today:
If you moved to Dubai in the last one to three years and your health has shifted since, note down what changed and when. Research suggests that timing of symptoms relative to a major life change — like relocation — is clinically meaningful information. Bring it to your next healthcare appointment.
