Welche Nährstoffmängel treten nach einer bariatrischen Operation häufig auf?

Welche Mängel?

Am häufigsten kommt es zu einem Mangel an Kalzium, Vitamin B12, Folsäure (Vitamin B9), Vitamin B1, Kupfer, Zink, Eisen und den fettlöslichen Vitaminen D, A und E. Abhängig von Ihren Blutwerten kann es notwendig sein, neben einem Multivitamin-/Mineralstoffpräparat und einem Kalziumpräparat den Mangel durch eine zusätzliche Eisen- oder Vitamin-B12-Ergänzung auszugleichen.

Denken Sie daran, dass herkömmliche Nahrungsergänzungsmittel nach einer bariatrischen Operation nicht ausreichen, da sie zu niedrig dosiert sind und nicht gut aufgenommen werden. Entscheiden Sie sich daher immer für spezielle adipöse Nahrungsergänzungsmittel, um in Form zu bleiben.

Wie erkennt man Engpässe?

Vitamin- und Mineralstoffmangel entwickelt sich meist schleichend. Am Anfang mögen die Symptome eher vage sein, doch mit der Zeit werden sie immer deutlicher. Vitamin- und Mineralstoffmängel müssen regelmäßig durch Blutanalysen festgestellt werden. Sprechen Sie mit Ihrem Hausarzt über Ihre Operation. Stellen Sie sicher, dass Sie Ihr Blut regelmäßig in dem Zentrum, in dem Sie operiert wurden, oder bei Ihrem Hausarzt untersuchen lassen (im 1. Jahr alle 3 Monate, im 2. Jahr alle 6 Monate und dann jedes Jahr).

Consequences of deficiencies?

General vitamin and mineral deficiency

Deficiency of minerals (such as zinc, magnesium, iron, copper, calcium, … ) and vitamins (such as vitamin A, B1, B6, B9, B12, C, D, E, …) deficiency leads to reduced health. Typical complaints are fatigue, trouble concentrating, insomnia, listlessness, muscle cramps, hair loss, …

General calcium deficiency

Calcium is important for bone formation and for the maintenance of strong bones. In case of long-term calcium deficiency, the body will extract calcium from the bones. This may lead to osteoporosis or bone decalcification and/or bone fractures. You may also suffer from confusion, forgetfulness, muscle cramps, muscle weakness, … 

Specific vitamin B12 deficiency

Vitamin B12, a water-soluble  vitamin, is important for the production of red blood cells and for a normal functioning of the nerves and brains. Vitamin B12 has to bind to the “Intrinsic Factor”  for absorption into the body. The “Intrinsic Factor” is produced in the stomach. When part of the stomach has been removed, little to no intrinsic factor can be produced. Vitamin B12 deficiencies are thus inevitable. Lasting vitamin B12 deficiencies may lead to anemia through a decrease of the number of red blood cells, but also to neurological problems such as muscle weakness, confusion, forgetfulness, increased irritability, …

Specific iron deficiency

Iron is an important mineral that supports the production of red blood cells and helps to fight fatigue. An iron deficiency will be noticeable quite quickly: lack of energy, fatigue, headache, dizziness, concentration problems… A clear iron deficiency may reduce your immunity, leading to increased risk of diseases.

Specific vitamin D deficiency

Vitamin D is a fat soluble vitamin, obtained partly from sun exposure (UV light), through the skin, and partly from food. Vitamin D ensures a good immunity and strong bones and teeth by helping with the absorption of calcium and phosphorus from nutrition. In case of a lack of sun exposure and/or a low dietary intake, vitamin D deficiency may occur. Moreover, vitamin D deficiencies are very common among people who have undergone bariatric surgery. That is because vitamin D is stored mainly in the fat mass, as a result of which these people run a great risk of having a vitamin D deficiency already before bariatric surgery. A lasting vitamin D deficiency may lead to several disorders.

Don’t forget the proteins

Proteins are the building blocks of our bodies (bones) and help maintain muscle mass. In case of a lack of proteins, muscle atrophy may occur. After bariatric surgery, it may be difficult to take the daily recommended amount of proteins through nutrition. Supplementation may be recommended to help achieve this goal.
